DISS. ETH Nr. 18904 GENERAL PRINCIPLES OF CELLULAR ORGANIZATION IN THE GENOME-REDUCED BACTERIUM MYCOPLASMA PNEUMONIAE A dissertation submitted to the SWISS FEDERAL INSTITUTE OF TECHNOLOGY ZURICH for the degree Doctor of Sciences presented by SEBASTIAN KÜHNER Dipl. Biol., Ruprecht-Karls-University Heidelberg born July 31, 1981 German citizen Accepted on the recommendation of: Prof. Dr. Ruedi Aebersold, examiner Dr. Anne-Claude Gavin, co-examiner Prof. Dr. Uwe Sauer, co-examiner 2010 Zusammenfassung Eines der Ziele naturwissenschaftlicher Forschung ist es, eine selbstreplizierende Zelle in ihrer Gesamtheit zu verstehen. Kennt man die organisatorischen Prinzipien, denen grundlegende Bestandteile der Zelle, wie Transkriptom, Proteom und Metabolom unterliegen, so ist man diesem Ziel einen bedeutenden Schritt näher. In den vergangenen Jahren haben enorme technische Fortschritte bei analytischen Hochdurchsatzverfahren die systematische Untersuchung dieser einzelnen „Ome“ ermöglicht. Dies wiederrum gibt uns heute die Gelegenheit, in einem Organismus parallel das Transkriptom und seine Komplexität, die Proteomorganisation in Proteinkomplexe sowie den Metabolismus und dessen Regulation global zu analysieren. Die vorliegende Doktorarbeit beschreibt die systematische Charakterisierung dieser zellulären Bestandteile in dem genomreduzierten Bakterium Mycoplasma pneumoniae, das zu den kleinsten sich selbstständig fortpflanzenden Lebensformen zählt. Der Fokus dieser Arbeit liegt auf der Analyse der Proteomorganisation, der Studie zu der ich, im Vergleich aller drei Teilstudien, den mit Abstand größten Teil beigetragen habe. Zur Untersuchung der grundlegenden Prinzipien bakterieller Proteomorganisation führten wir eine proteomweite, auf chromatographischer Aufreinigung sowie massenspektrometrischer Analyse von Proteinkomplexen basierende Studie durch. Die Datenanalyse identifizierte 62 homopolymere und 116 heteropolymere, lösliche Proteinkomplexe, von denen die Mehrzahl bisher uncharakterisiert ist. Etwa ein Drittel der heteropolymeren Komplexe ist an der Bildung komplexerer Formen der Proteomorganisation beteiligt. Dazu zählt die Anordnung in größere Multiproteinkomplexeinheiten, welche zum Teil die sequentiellen Schritte eines biologischen Prozesses reflektieren. Des weiteren beobachten wir, dass ein und dasselbe Protein Bestandteil mehrerer verschiedener Komplexe sein kann, was wir als Proteinmultifunktionalität interpretieren. Dies könnte eine mögliche Erklärung für die Genomreduzierung Proteinkomplexdaten von mit elektronentomographischen M. pneumoniae 484 darstellen. Proteinstrukturen, Daten liefert Kombination der elektronenmikroskopischen und zusätzliche Die strukturelle Details der Proteomorganisation dieses Bakteriums. Um die grundlegenden Prinzipien des bakteriellen Metabolismus und seiner Regulation zu verstehen, wurde ein metabolisches Netzwerk aus 129 Enzymen, die insgesamt 189 verschiedene Reaktionen katalysieren, konstruiert. Die Nutzung dieses biochemischen Atlas ermöglichte es, ein Minimalmedium, bestehend aus 19 essentiellen Bestandteilen, zu entwickeln. Das metabolische Netzwerk von M. pneumoniae hat im Vergleich zu General principles of cellular organization in Mycoplasma pneumoniae komplexeren Bakterien eine stärker lineare Topologie und enthält einen höheren Anteil an multifunktionalen Enzymen. Allgemeine Eigenschaften wie die Konzentration von Metaboliten, der zelluläre Energiehaushalt, die Anpassungsfähigkeit und die globale Genexpression sind denen anderer Bakterien ähnlich. Für die Transkriptionsanalyse wurde strangspezifische Mikrochiptechnologie „Tilingarrays“, ergänzt durch die direkte Sequenzierung der Transkripte, mit mehr als 252 Spottedarrays kombiniert. Es wurden 117 neue, meist nicht-codierende Transkripte, von denen 89 in antisense Konfiguration zu bekannten Genen liegen, detektiert. Weiterhin wurden 202 monocistronische sowie 139 polycistronische Operons identifiziert, wobei fast die Hälfte der letzteren ein stufenartiges Transkriptionsprofil aufweist. Unter variierenden Wachstumsbedingungen können sich die Operons in bis zu 447 kleinere transkriptionelle Einheiten aufteilen, was die Mannigfaltigkeit der alternativen Transkripte erklärt. Häufige antisense und alternative Transkripte sowie unterschiedliche Regulationsmechanismen verdeutlichen die hohe Dynamik dieses Transkriptoms. Die Informationen in dieser Doktorarbeit können als kleiner Teil eines Bauplans für eine minimale zelluläre Maschine angesehen werden. Die vier allgemeinen Schlußfolgerungen aus dieser Arbeit sind: 1. M. pneumoniae weist besonders in seiner Proteomorganisation und in seinem Metabolismus Aspekte der Multifunktionalität auf. 2. M. pneumoniae ist für einen nahezu minimalen Organismus, bezüglich seiner regulatorischen Prozesse, deutlich komplexer als erwartet. 3. M. pneumoniae ähnelt Eukaryoten, hinsichtlich Komplexität seines Transkriptoms, wesentlich stärker als erwartet. 4. M. pneumoniae ist auf Wirtsanpassung und nicht auf maximales Wachstum optimiert. General principles of cellular organization in Mycoplasma pneumoniae Summary One aim of research in natural sciences is to understand a self-reproducing cell in its entity. Transcriptome, proteome and metabolome are at the heart of cellular organization. To know the general principles underlying these basic functional aspects of a cell is a key part on the way to comprehensively understand cellular life. In recent years systematic analysis of the individual “omes” has been facilitated via dramatically advancing analytical high-throughput techniques. This opened opportunities to globally investigate the transcription and its complexity, the proteome organization into protein complexes as well as the metabolism and its regulation of an entire organism. In the presented PhD thesis I describe an effort to systematically characterize these features for the genome-reduced organism Mycoplasma pneumoniae, which is among the smallest self-replicating forms of life on earth. My work hereby focuses on the analysis of the proteome organization, the part, among the three investigations, to which I contributed most substantially. In order to study basic principles of bacterial proteome organization, we used tandem affinity purification followed by mass spectrometric analysis to investigate protein complexes in a proteome-wide screen. The analysis revealed 62 homomultimeric and 116 heteromultimeric soluble protein complexes, of which the majority are novel. About a third of the heteromultimeric complexes show higher levels of proteome organization, including assembly into larger, multi-protein complex entities, suggesting sequential steps in biological processes, and extensive sharing of components implying protein multifunctionality. Incorporation of structural models for 484 proteins, single particle EM and cellular electron tomograms provided supporting structural details for this proteome organization. To understand basic principles of bacterial metabolism and its regulation, a manually curated metabolic network of 129 enzymes catalyzing 189 reactions was constructed. This metabolic map allowed the design of a defined, minimal medium with 19 essential nutrients. In summary, the M. pneumoniae metabolic network has a more linear topology and contains a higher fraction of multifunctional enzymes compared to more complex bacteria; general features such as metabolite concentrations, cellular energetics, adaptability and global gene expression responses are similar though. For the transcriptome analysis we combined strand-specific tiling arrays, complemented by transcriptome sequencing, with more than 252 spotted arrays. We detected 117 previously undescribed, mostly non-coding transcripts, 89 of them in antisense configuration to known genes. We identified 202 monocistronic and 139 polycistronic operons; almost half of the latter show decaying expression in a staircase-like manner. Under various conditions, operons General principles of cellular organization in Mycoplasma pneumoniae could be divided into 447 smaller transcriptional units, resulting in many alternative transcripts. Frequent antisense transcripts, alternative transcripts, and multiple regulators per gene imply a highly dynamic transcriptome. In essence this thesis dataset provides a blueprint of the minimal cellular machinery required for life. The four general conclusions of this work are that: 1. M. pneumoniae shows aspects of multifunctionality particularly in its proteome organization and metabolism. 2. M. pneumoniae, even though being an almost minimal organism, is more complex than expected, particularly in its regulation. 3. M. pneumoniae resembles eukaryotes more than expected, particularly in its transcription. 4. M. pneumoniae is optimized for host adaptation and not for growth.

M. pneumoniae – a genome reduced model organism The following subchapters will first give an overview on the historic development of research on M. pneumoniae. Secondly, its key pathogenic aspects are summarized and in a third part I provide selected arguments as to why M. pneumoniae is a suitable model organism for systematic studies. 1.1.1. History of research in M. pneumoniae The history of the term “mycoplasma”, from the Greek “mykes”, which translates to fungus and “plasma” meaning formed, dates back to the year 1889, when A. B. Frank illustrated the special relationship between plant-invading fungi or other microorganisms and their host cells (Frank 1889; Krass and Gardner 1973). The initial discovery of Mycoplasma, i.e. the first isolation of the contagious bovine pleuropneumonia (CBPP) agent, to date known as Mycoplasma mycoides subsp. mycoides, is credited to Nocard and Roux in the year 1898 (Nocard and Roux 1898; Razin, Yogev et al. 1998; Waites and Talkington 2004). Subsequently, the nomenclature pleuro pneumonia-like organisms (PPLO) was chosen for microorganisms in the genus Mycoplasma, referring to life forms similar to the causative agent of CBPP (Edward, Meiklejohn et al. 1956). It has to be noted though that the fungus like growth pattern described by the name “Mycoplasma” does only coincide with the growth characteristics of Mycoplasma mycoides. Nevertheless the name Mycoplasma was adopted for the entire genus (Razin, Yogev et al. 1998; Waites and Talkington 2004). Since the 1960s Mycoplasmas are considered as members of a bacterial class named Mollicutes. This name is derived form the Latin words “mollis” and “cutis” meaning soft skin (Razin, Yogev et al. 1998) (Figure 1). Their soft skinned properties are the consequence of the absence of a cell wall. The cellular membrane is however stiffened by the insertion of sterols. In current taxonomy the class of Mollicutes is part of the phylum tenericutes within the bacterial kingdom. It comprises 4 orders, 5 families, 8 genera and approximately 200 species (Razin, Yogev et al. 1998; Waites and Talkington 2004). General principles of cellular organization in Mycoplasma pneumoniae 1 Figure 1 M. pneumoniae amongst its bacterial relatives zoomed in from the tree of life (from http://itol.embl.de/) (Ciccarelli, Doerks et al. 2006). In blue the genome size (in number of genes) is shown next to each organism. The species highlighted in red are bacteria closely related to M. pneumoniae that are used as benchmarks within this work. Mycoplasma pneumoniae is a member of the family of Mycoplasmataceae and the order of Mycoplasmatales. M. pneumoniae was originally isolated from the sputum of a patient with primary atypical pneumoniae by Eaton, Meiklejohn and van Herick in 1944 and was hence termed “Eaton’s agent” or “primary atypical pneumonia virus” (Eaton, Meiklejohn et al. 1944; Waites and Talkington 2004). In a concerted reclassification call in 1963 several microbiological experts proposed to rename Eaton’s agent to Mycoplasma pneumoniae (Chanock 1963). They did so because M. pneumoniae growth, although being unaffected by microbial inhibitors such as thallium acetate, penicillin and amphotericin B, is sensitive to the tetracycline group of antibiotics and therefore most likely of bacterial and not viral origin (Chanock 1963). In the following years the characterization of M. pneumoniae focused mainly on its biochemical, cell biological as well as pathogenic properties. In 1966 Prescott, Sobeslavsky and colleagues used chemical and chromatographic separation techniques in two back to back studies reporting the isolation and characterization of different cellular fractions of M. pneumoniae together with the investigation of their antigenic properties (Prescott, Sobeslavsky et al. 1966; Sobeslavsky, Prescott et al. 1966). These studies General principles of cellular organization in Mycoplasma pneumoniae 2 revealed a high immunogenicity of fractionated lipids combined with protein in complexes, while lipids alone were only a weakly immunogenic (Prescott, Sobeslavsky et al. 1966; Sobeslavsky, Prescott et al. 1966). In addition to such studies the ultra structure of M. pneumoniae was investigated in detail using scanning and transmission electron microscopy (Biberfeld and Biberfeld 1970; Kammer, Pollack et al. 1970; Knudson and MacLeod 1970; Boatman and Kenny 1971; Wilson and Collier 1976). The three major messages of these studies were that i) M. pneumoniae has a highly structured, basic protein rich, electron dense rod structure at its thinner end (Tip region, attachment organelle), which is surrounded by electron-lucent cytoplasm and the cell membrane (Biberfeld and Biberfeld 1970; Wilson and Collier 1976) ii) M. pneumoniae undergoes an ordered and sequential metamorphosis during its life cycle involving spherical and filamentous forms (Kammer, Pollack et al. 1970); M. pneumoniae being pleomorph (Knudson and MacLeod 1970) iii) Nucleic acids present within M. pneumoniae appear to be excluded from the tip region and mostly located in cytoplasmic granules (Wilson and Collier 1976). An important cell biological feature that enables M. pneumoniae to survive without a cell wall is its internal cytoskeleton, which supports the integrity of the cellular membrane (Krause and Balish 2001; Krause and Balish 2004; Balish and Krause 2006). The cytoskeleton is structurally and compositionally novel in comparison to the cytoskeletons of other organisms, including other bacteria, and it is involved in the cell division process (Balish and Krause 2006). Furthermore it is associated with the terminal attachment organelle, and proves to be essential for colonization of the host as well as for gliding motility (Balish and Krause 2006). Regarding M. pneumoniae cellular motility Radestock and Bredt observed that: “The cells moved in an irregular pattern with numerous narrow bends and circles. They never changed their leading end. The average speed was relatively constant between 0.2 and 0.5 µm/s. The maximum speed was about 1.5 to 2.0 µm/s.” (Radestock and Bredt 1977). Furthermore it was observed that the gliding motility of M. pneumoniae cells required an intact energy metabolism and is susceptible to changes in pH, temperature, viscosity and various other factors (Radestock and Bredt 1977). In recent years mutant analysis revealed requirement of the protein P30 (Mpn453) in M. pneumoniae gliding motility (Hasselbring, Jordan et al. 2005); via a transposon mutagenesis approach additional genes associated with gliding motility were identified (Hasselbring, Page et al. 2006). Just in the same year it was shown that the separation of terminal organelles was impaired in a non motile mutant, indicating a requirement for gliding motility in regular cell division (Hasselbring, Jordan et al. 2006) General principles of cellular organization in Mycoplasma pneumoniae 3 With regard to understanding M. pneumoniae’s pathogenic properties two major advances have been achieved towards in the mid 1980s. First, the involvement of the P1 surface protein (Mpn141), that is located within the attachment organelle, in M. pneumoniae infection of human host cells has been highlighted (Baseman, Cole et al. 1982; Feldner, Gobel et al. 1982; Hu, Cole et al. 1982). Secondly, there was progress on the more detailed understanding of the specificity of the interaction of M. pneumoniae with human erythrocytes. Here the lab of Ten Feizi, a specialist on glycobiology and M. pneumoniae research, discovered that erythrocyte receptors for M. pneumoniae are sialylated oligosaccharides (Loomes, Uemura et al. 1984). In the late 1990s until the first decade of the 21st century M. pneumoniae research was highly driven by technical advances on genome sequencing, which leveraged research in virtually all aspects of the life sciences. In 1996 the genome of M. pneumoniae was amongst the first to be completely sequenced. This work has been directed by Richard Herrmann, an outspoken expert on M. pneumoniae biology (Himmelreich, Hilbert et al. 1996) who was also involved in a re-annotation that followed four years later (Dandekar, Huynen et al. 2000). Currently the M. pneumoniae genome contains 689 annotated genes and about 816kbp. Finally, it seem worthwhile to notice that among the human mycoplasmas M. pneumoniae is by far the best known and most carefully studied (Razin, Yogev et al. 1998; Waites and Talkington 2004). 1.1.2. Pathogenicity of M. pneumoniae Mycoplasmas in general are mucosal pathogens, which survive as parasites in close association with their hosts (Waites and Talkington 2004). M. pneumoniae in particular is a pathogenic bacterium exclusive to humans that colonizes lung epithelia (Waites and Talkington 2004). It causes a respiratory illness that mainly affects children as well as adolescents and during which cold agglutinins develop (Chanock 1963; Razin, Yogev et al. 1998; Hammerschlag 2001; Herrmann and Ruppert 2006). According to O’Donnell and colleagues “the clinical syndrome is characterized by findings that are atypical for the usual bacterial pneumonia: a lack of fever or systemic symptoms, negative cultures, unusual radiographic features, or a combination of these” (O'Donnell, Kradin et al. 2004). Hence the disease is termed “atypical pneumonia”. Also, in contrast to pneumonia caused by the more traditional pathogens Streptococcus pneumoniae or Haemophilus influenzae, it does not respond to the usual antibiotic treatment. It was already noted that M. pneumoniae growth is unaffected by a number of antibiotics and that the bacterium is sensitive to gentamycin as well as the tetracycline group of microbial inhibitors. To that end it is remarkable that the M. General principles of cellular organization in Mycoplasma pneumoniae 4 pneumoniae RNA polymerase shows resistance to rifampin, due to a point mutation, whereas other eubacteria can be successfully treated with this antibiotic. Another striking feature of M. pneumoniae is that it fulfils all four of Koch’s postulates (Rifkind, Chanock et al. 1962; Smith, Chanock et al. 1967; Clyde 1973). The postulates are criteria, formulated by Robert Koch and Friedrich Loeffler in the late 19th century, which are designed to establish a relationship between a causative microbe and a disease. The postulates are as follows: 1. The bacteria must be present in every case of the disease. 2. The bacteria must be isolated from the host with the disease and grown in pure culture. 3. The specific disease must be reproduced when a pure culture of the bacteria is inoculated into a healthy susceptible host. 4. The bacteria must be recoverable from the experimentally infected host. A prerequisite for M. pneumoniae pathogenicity is the tight connection to epithelial host cells via its attachment organelle. The attachment organelle mediating this adhesion is located in the tip structure of the cell (Figures 10 &15). Consequence of such strong adhesion is the impaired removal via the mucociliary clearance machinery of the host (Waites and Talkington 2004). Within the last decades several reports were published that included microbiological-, animalas well as human volunteer tests, which have assessed the infectious properties of M. pneumoniae (Smith, Chanock et al. 1967; Lipman, Clyde et al. 1969; Hansen, Wilson et al. 1979; Hansen, Wilson et al. 1979; Hansen, Wilson et al. 1981; Hansen, Wilson et al. 1981; Leith, Hansen et al. 1983; Franzoso, Hu et al. 1993; Franzoso, Hu et al. 1994; Catrein, Dumke et al. 2004; Dumke, Catrein et al. 2004). Lipman et al. derived pairs of virulent and attenuated or avirulent M. pneumoniae strains and compared them in an effort to elucidate the mechanisms of virulence (Lipman, Clyde et al. 1969). They found that variations in the morphology as well as its cytadsorption characteristics closely correlated with avirulence in the case of M. pneumoniae strain M129-B169 (where the 169 indicates the number of passage in broth medium: B) (Lipman, Clyde et al. 1969). In a separate investigation Hansen and colleagues report a similar strain derived from virulent M. pneumoniae M129 that is rapidly cleared from lungs of infected hamsters (Hansen, Wilson et al. 1981). Subsequent studies revealed that two proteins, a 40 and 90-kDa protein (Mpn142), which are present in cytadsorbing, pathogenic wild-type strains are absent in the non-pathogenic strain M129B176 (Hu, Collier et al. 1977; Baseman, Cole et al. 1982; Hu, Cole et al. 1982). These two General principles of cellular organization in Mycoplasma pneumoniae 5 proteins are surface exposed, localized on the terminal tip apparatus, and likely to be involved in the attachment mechanism (Franzoso, Hu et al. 1993). These two proteins are products of the mpn142 gene that encodes a membrane protein moiety, a leader signal, and a stop-transfer sequence and produces the 90- and the 40-kDa protein instead of an expected 130-kDa protein (Sperker, Hu et al. 1991; Franzoso, Hu et al. 1993). Another protein with major importance for host recognition is the adhesin P1 (Mpn141). Until today there have been numerous reports that highlight the major role of P1, which is concentrated in the tip structure and is a major component of the virulence mediating interaction of M. pneumoniae with host cells (Ruland, Wenzel et al. 1990; Layh-Schmitt and Herrmann 1992; Seto, Layh-Schmitt et al. 2001; Hasselbring, Page et al. 2006; Seybert, Herrmann et al. 2006). To conclude this subchapter on pathogenicity, I want to remark that M. pneumoniae, although being classified as an S2 (security standard) organism, is certainly not the most clinically relevant organism causing acute pneumonia. Nevertheless it is essential to always perform laboratory work according to good laboratory practices adjusted to S2 standards and with the common sense of dealing with a pathogen. Yet the pathogenic aspects have not been the major source of motivation for us to embark in a project with M. pneumoniae but rather the idea to employ it as a model system for studying a “minimal organism” as depicted in the next subchapter. 1.1.3. Establishing M. pneumoniae as a model organism for systematic studies Mollicutes are, based on 16S RNA investigations classified as, gram-positive bacteria and are generally characterized by their strikingly small genomes (Figure 1) (Fraser, Gocayne et al. 1995; Himmelreich, Hilbert et al. 1996). These genomes consist of a single circular chromosome containing 0.58 to 2.2 Mbps and are thus the smallest known genomes of freeliving organisms. Therefore Mycoplasmas have attracted much attention as blueprints of minimal cells. The M. pneumoniae genome for example encodes for 689 protein coding genes and 44 ncRNAs. M. genitalium, which could be considered as a deletion mutant of M. pneumoniae and is its phylogenetically closest relative, consists of only 485 protein coding genes (Figure 1). In comparison to the standard model bacteria E. coli and B. subtilis the M. pneumoniae genome is about 7 times smaller in terms of both base pairs and number of genes (Table 1). The same holds true for its cellular volume, which is only 10% of that of E. coli and less than 5% of that of a typical Bacillus like e.g. B. subtilis (Table 1) (Waites and Talkington 2004). Similarly, the total number of mRNA molecules in E. coli is approximately 15 times larger than in M. pneumoniae (Table 1). General principles of cellular organization in Mycoplasma pneumoniae 6 Other arguments as to why M. pneumoniae is an ideal near-minimal organism for systematic studies are its minimal enzymatic toolbox. This reduced set suggests a controllable organism complexity. For instance, the M. pneumoniae genome encodes for only one protein phosphatase and two protein kinases creating an absolutely minimal phosphorylation regulatory network. The same minimalism is evident for the current knowledge about other PTMs. Apart from phosphorylation only three other PTMs are reported, which include two variations of protein cleavage as well as modification with lipids. On a genome regulatory level there are additional arguments underlining the parsimonious way in which M. pneumoniae deals with its resources, e.g. genome annotations identified only one sigma factor (Himmelreich, Hilbert et al. 1996; Dandekar, Huynen et al. 2000; Weiner, Zimmerman et al. 2003). Feature / cell M. pneumoniae E. coli # total DNA bp 816,394 4,639,675 # ORFs 689 4,132 # Ribosomes 140 18,000 # mRNAs 230 4,000 Cell volume [L] 6.7x10-17 6.7x10-16 Protein weight [fg] 10 165 Table 1 Benchmarking M. pneumoniae against the classic model bacterium E. coli. Data from this table originates from NCBI databases and (Guell, van Noort et al. 2009; Yus, Maier et al. 2009) Apart from all positive aspects that make M. pneumoniae an ideal model organism for systematic studies there are also pitfalls to this bacterium. One major disadvantage is the elongated generation time of 8 hours. Compared to E. coli, which divides every 20 minutes this is considerably slower and makes research in M. pneumoniae more time-consuming. Additionally this could severely hamper its applicability for biotechnological and engineering purposes. A second drawback is the adherent life-style of M. pneumoniae, which enables the growth of wild-type cells only in a two dimensional fashion. In consequence the amount of cells that can be cultivated at once in comparison to bacterial suspension cultures is limited, causing additional costs for culture equipment and manpower if larger cultures are to be grown. However, the disadvantage of growing M. pneumoniae in an adherent fashion can be circumvented by using non-adherent mutants such as the M. pneumoniae strain B176. This mutant lacks parts of its attachment organelle causing the non-adherence and it has moreover been reported to be avirulent. General principles of cellular organization in Mycoplasma pneumoniae 7 Along the lines of using Mycoplasmas as a blueprint of minimal cells a team around John I. Glass, Clyde A. Hutchison, Hamilton O. Smith and Craig Venter at the J. Craig Venter Institute uses the close M. pneumoniae relative M. genitalium as a model organism for synthetic biology. In a project that started more than 15 years ago they first sequenced the M. genitalium genome (Fraser, Gocayne et al. 1995). In a following step transposon mutagenesis was globally applied to identify nonessential genes in M. pneumoniae and M. genitalium. Conversely this dataset then provides insight into the essential gene complement of the minimal organism. In their first analysis Hutchison et al. report that about 265 to 350 of the M. genitalium genes are essential under laboratory growth conditions, including about 100 proteins of unknown function (Hutchison, Peterson et al. 1999). In a second analysis of that kind Glass et al. describe 382 of the protein coding genes as essential, with 28% of them being of unknown function (Glass, Assad-Garcia et al. 2006). Just recently, the chemical synthesis of a complete M. genitalium genome was reported (Gibson, Benders et al. 2008). In another effort this team managed to perform a genome transplantation taking M. mycoides genomic DNA and transplanting it into M. capricolum cells. The successful transplants were phenotypically identical to the DNA donor cells of M. mycoides (Lartigue, Glass et al. 2007). Following this transplantation report, the subsequent step was the transplantation of Mycoplasma DNA into yeast to exploit its mechanism of homologous recombination for highly efficient genetic modifications in order to create novel M. mycoides strains (Lartigue, Vashee et al. 2009). All mentioned technological advances above could most likely also be applied to M. pneumoniae. Due to these advantageous characteristics and as M. pneumoniae is the best studied species among the Mycoplasmas M. pneumoniae appears to be a suitable model organism for systematic studies. General principles of cellular organization in Mycoplasma pneumoniae 8 1.2. Studying M. pneumoniae at different levels This subchapter introduces the state of the art of research prior to the studies that are described in chapters 2 to 4. For that reason this part of the introduction is already structured according to the research aspects of the individual studies focusing on the proteome, the metabolism and the transcriptome of M. pneumoniae. 1.2.1. Proteome of M. pneumoniae A proteome is the entire set of proteins that are expressed in an organism at a given condition and time point. In the case of M. pneumoniae, proteomic studies have been conducted for almost half a century. Initially these investigations focused mainly on one gene product at a time. With the emergence of more sophisticated analytical tools, namely the use of mass spectrometers for peptide and hence protein identification, global analysis of the M. pneumoniae proteome became more widespread. The first of these studies by Regula and coworkers characterized the proteome via a two-dimensional gels electrophoresis (Regula, Ueberle et al. 2000). Overall, 350 protein spots were analysed from various 1-D and 2-D gel electrophoresis setups using diverse pH gradients as well as two different mass spectrometers (Regula, Ueberle et al. 2000); they were assigned to 224 genes (Regula, Ueberle et al. 2000). In a follow up effort this proteome map was extended to 305 gene products identified using advanced chromatographic techniques (Ueberle, Frank et al. 2002). This new map corresponded to 44% coverage of the at that time 688 annotated genes (Ueberle, Frank et al. 2002). Two years later Jaffe and colleagues increased the proteome coverage in M. pneumoniae to 81% applying an approach called proteogenomic mapping (Jaffe, Berg et al. 2004). They mapped peptides detected in a whole-cell lysate of M. pneumoniae onto a genomic scaffold and extended these hits into ORFs bound by traditional genetic signals to generate the “proteogenomic map” (Jaffe, Berg et al. 2004). They detected 9,709 unique peptides corresponding to 557 of the now 689 predicted ORFs (This includes annotated genes with mpn numbers 1 to 688 and an additional gene called mpn528a) (Jaffe, Berg et al. 2004). Subsequent to this study by Jaffe et al. a review by Herrmann and Ruppert summarized the status of the M. pneumoniae proteome prior to the investigation described in this thesis (Herrmann and Ruppert 2006). They counted a total of 565 proteins that were experimentally identified out of 689 protein coding genes annotated (82% coverage) (Herrmann and Ruppert 2006). From the 689 protein coding genes annotated, by the NCBI via their system of COGs, General principles of cellular organization in Mycoplasma pneumoniae 9 190 do not fit any COGs, while another 16 have an unknown function and 54 have a general function prediction only (Herrmann and Ruppert 2006). This leaves 429 (of the 689) annotated genes with a functional description according to COGs. Another very important aspect of proteome research is that it benefits largely from integration of additional data such as protein-protein interactions or protein structures in order to functionally describe a cell. Regarding the systematic characterization of protein complexes and the mapping of binary protein-protein interactions major efforts have been reported for other bacteria such as Campylobacter jejuni, E. coli or Helicobater pylori amongst others (Rain, Selig et al. 2001; Butland, Peregrin-Alvarez et al. 2005; Arifuzzaman, Maeda et al. 2006; Parrish, Yu et al. 2007; Hu, Janga et al. 2009). For M. pneumoniae, a systematically derived binary proteinprotein interaction network and a global catalogue of protein complexes are yet missing. Concerning the solution of protein structures considerable effort has been undertaken by the Berkeley Structural Genomics Center to obtain a near-complete structural complement of the minimal genomes of M. genitalium and M. pneumoniae. Altogether this initiative has currently solved 90 structures from 59 targets, which are subject to various publications (Chen, Yakunin et al. 2005; Shin, Kim et al. 2006; Das, Hyun et al. 2007). Taking into account related structures from close orthologs brings the total number of M. pneumoniae proteins for which a structure or model is available to ~350 (Kim, Shin et al. 2005; Chandonia and Kim 2006). Thus the community is not that far away from a structurally solved organism. Together with additional orthogonal initiatives this will assist in adding value to data produced by classical proteomics experiments on the way to the systematic functional description of this bacterial cell. 1.2.2. Metabolism of M. pneumoniae In simple analogy to the genome of M. pneumoniae, its metabolism, the entity of all biochemical reactions, which this organism can perform autonomously, is extremely reduced and tailored towards the needs of a parasitic lifestyle closely associated with the host. Therefore M. pneumoniae has a very limited enzymatic toolbox including for instance only one protein phosphatase and two protein kinases. This might have a direct impact on the regulatory capabilities via, e.g. phosphorylation. As M. pneumoniae, like all mollicutes, misses enzymes for peptidoglycan synthesis encoded in its genome it permanently lacks a cell wall (Razin, Yogev et al. 1998; Waites and Talkington 2004). This confers pleomorphism and aggravates their taxonomical classification. General principles of cellular organization in Mycoplasma pneumoniae 10 Another consequence of the absence of a cell wall is that the maintenance of osmotic stability is especially important even though the pathogen stiffens its membrane with cholesterol insertions (Razin, Yogev et al. 1998; Waites and Talkington 2004). At yet another end of the M. pneumoniae biochemical pathways map it has been reported that purine and pyrimidine metabolism is sufficient for enabling the synthesis of RNA and DNA in this near-minimal cell based on nucleic acid precursors (Pachkov, Dandekar et al. 2007). A review of the central carbohydrate metabolism revealed that M. pneumoniae possesses all 10 reactions of Glycolysis but tricarboxylic acid cycle and cytochrome mediated electron transfer chains are however absent (Pollack, Myers et al. 2002; Waites and Talkington 2004). Besides ATP generation via glycolysis M. pneumoniae is known to be capable of lactic acid fermentation like various other bacteria (Razin, Yogev et al. 1998; Waites and Talkington 2004). This is a process of anaerobic respiration that converts sugars such as glucose, fructose, or sucrose into cellularly amenable energy via substrate phosphorylation effected by phosphoglycerate kinase (Mpn429) and pyruvate kinase (Mpn303), while the metabolic product lactic acid is formed (Waites and Talkington 2004). Other metabolic peculiarities that M. pneumoniae shares with most mollicutes lie within the way these bacteria regulate translation. For instance, M. pneumoniae uses the universal stop codon UGA as an alternative codon for tryptophan (Inamine, Ho et al. 1990). Additionally the M. pneumoniae genome sequencing revealed the absence of generic Shine-Dalgarno sequences, especially in comparison to other known, related genomes including e.g. B. subtilis (Himmelreich, Hilbert et al. 1996; Osada, Saito et al. 1999; Sakai, Imamura et al. 2001). These sequences are ribosomal binding sites to the mRNAs, generally located upstream of the start codon AUG and show a characteristic consensus sequence among many other bacterial classes. Finally, a remark to the generic growth medium so called “Hayflick medium” that has been used for M. pneumoniae research purposes in the last decades (Hayflick 1965). It provides glucose as the major carbon source feeding the energy metabolism. Hayflick medium, however is an undefined medium, as it contains horse serum. Furthermore it has not been comprehensively characterized for its minimal components. From the point of view of complete parameter control, which is prerequisite for optimal experimental reproducibility, this is certainly a weakness of Hayflick medium especially in the analysis of the biochemical properties of M. pneumoniae. General principles of cellular organization in Mycoplasma pneumoniae 11 1.2.3. Transcriptome of M. pneumoniae Besides their remarkably small sizes the Mollicutes genome’s are characterized by an extremely low GC content (23 to 40%) (Razin, Yogev et al. 1998). This holds true for the genome of M. pneumoniae (40%), too. Within the years following the completion of the M. pneumoniae genome sequence, research has focused on the control of gene expression (Weiner, Herrmann et al. 2000). From the analysis of the genomic sequences of M. pneumoniae and M. genitalium it became obvious, that major regulators of gene expression in other bacteria are missing (Fraser, Gocayne et al. 1995; Himmelreich, Plagens et al. 1997; Weiner, Herrmann et al. 2000); this includes the absence of the two component system and the Rho factor as well as the presence of a very limited number of σ factors (Himmelreich, Hilbert et al. 1996; Himmelreich, Plagens et al. 1997; Bairoch and Apweiler 2000). Interestingly, M. pneumoniae contains only one clearly identified σ factor (Mpn352), while a second putative σ factor, suggested to induce mobility in M. pneumoniae, has been proposed (Mpn626) (Bornberg-Bauer and Weiner 2002). The scarcity of σ factors in M. pneumoniae is in contrast to the at least 14 σ factors of its close relative B. subtilis (Bairoch and Apweiler 2000). Despite this apparent lack of complexity regarding its transcriptional regulation, part of the M. pneumoniae transcriptome, the entity of all RNAs (mRNA, rRNA, ncRNA) transcribed under varying conditions, has been shown to be regulated, e.g. by heat-shock, significantly increasing the expression of 47 genes including various known conserved heat shock genes including clpB (Mpn531), dnaJ (Mpn021), dnaK (Mpn434), groES (Mpn574) and lon (Mpn332) (Weiner, Zimmerman et al. 2003). Yet the transcriptome in M. pneumoniae has not been comprehensively characterized. Even though systematic gene expression studies have been reported for many other bacteria (Selinger, Cheung et al. 2000; Tjaden, Saxena et al. 2002; Reppas, Wade et al. 2006; McGrath, Lee et al. 2007; Nelson, Herron et al. 2008; Akama, Suzuki et al. 2009; ToledoArana, Dussurget et al. 2009), a complete dataset for M. pneumoniae is still missing. This limits the current understanding of the entire transcriptome in terms of its operon structures and regulation. Similarly, the number of classified ncRNAs in bacteria has recently been expanded (Vogel and Wagner 2007), however a comprehensive and unbiased repertoire is still missing and particularly underdeveloped in M. pneumoniae. To date the M. pneumoniae transcriptome consists of 689 annotated protein coding genes and 44 ncRNAs. General principles of cellular organization in Mycoplasma pneumoniae 12 1.3. Objectives of this PhD thesis Although M. pneumoniae is considered as the best known and most carefully studied species among the human mycoplasmas (Razin, Yogev et al. 1998; Waites and Talkington 2004) there are still vast parts of its biology unaddressed i.e. not understood. Consequently, current knowledge of the M. pneumoniae biology is lagging far behind that of other model organisms like E. coli or S. cerevisiae, especially considering the knowledge of tools for genetic engineering. However, as described in section 1.1.3, M. pneumoniae comes with the advantage of an extremely reduced genome, which allows genome-wide functional studies to be completed within the lifetime of a PhD thesis/student. This reduced genome size as well as the significantly reduced cellular dimensions, from which we infer a reduced organism complexity, are the main driving forces for us to globally investigate M. pneumoniae and establish it as a model organism for systematic studies on near-minimal organisms. In order to more systematically understand the general principles of cellular organization in M. pneumoniae the objectives of this PhD thesis are to elucidate: 1. its proteome organization, 2. its metabolism as well as its regulation and 3. its transcriptome complexity. Among these three projects, which are a combined effort of several research groups the focus of my work will be on the analysis of the proteome organization in M. pneumoniae. This includes the establishment of a library of M. pneumoniae strains in which all individual proteins are labeled with a TAP-tag. Using this collection I will perform a genome-wide screen for protein-protein interactions via TAP-MS to get an overview on the hetero- and homomultimeric protein complexes in this near-minimal bacterium. By integration of other datasets I want to address general questions like e.g. which molecular mechanisms must a self-sufficient organism use to still survive with such a reduced-genome. Additionally I would like to collaborate with experts on various structural biology techniques to exploit our proteinprotein interaction dataset in making the first steps towards solving the structural anatomy of a cell.

Abstract The genome of Mycoplasma pneumoniae is among the smallest found in self-replicating organisms. To study the basic principles of bacterial proteome organization, we used TAPMS in a proteome-wide screen. The analysis revealed 62 homomultimeric and 116 heteromultimeric soluble protein complexes, of which the majority are novel. About a third of the heteromultimeric complexes show higher levels of proteome organization, including assembly into larger, multi-protein complex entities, suggesting sequential steps in biological processes, and extensive sharing of components implying protein multifunctionality. Incorporation of structural models for 484 proteins, single particle EM and cellular electron tomograms provided supporting structural details for this proteome organization. The dataset provides a blueprint of the minimal cellular machinery required for life. General principles of cellular organization in Mycoplasma pneumoniae 15 2.3. Introduction Biological function arises in part from the concerted actions of interacting proteins that assemble into protein complexes and networks. Protein complexes are the first level of cellular proteome organization: functional and structural units – often termed molecular machines - that participate in all major cellular processes. Complexes are also highly dynamic in the sense that their organization and composition varies in time and space (de Lichtenberg, Jensen et al. 2005), and they interact to form higher level networks; this property is central to whole-cell functioning. However, general rules concerning protein complex assembly and dynamics remain elusive. The combination of affinity purification with MS (Rigaut, Shevchenko et al. 1999) has been applied to several organisms, providing a growing repertoire of molecular machines. Genomewide screens in Saccharomyces cerevisiae (Gavin, Aloy et al. 2006; Krogan, Cagney et al. 2006; Tarassov, Messier et al. 2008), captured discrete, dynamic proteome organization, and revealed higher order assemblies with direct connections between complexes and frequent sharing of common components. To date these exhaustive analyses have been applied only in yeast. In bacteria, genome-wide yeast two-hybrid analyses have been reported (Rain, Selig et al. 2001; Parrish, Yu et al. 2007), but only a few biochemical analyses on selected sets of complexes are available (Terradot, Durnell et al. 2004; Butland, Peregrin-Alvarez et al. 2005; Arifuzzaman, Maeda et al. 2006; Hu, Janga et al. 2009). The understanding of proteome organization in these organisms concerns thus the binary interaction networks. Here we report a genome-scale analysis of protein complexes in the bacterium, Mycoplasma pneumoniae, a human pathogen that causes atypical pneumonia (Waites and Talkington 2004). This self-replicating organism has one of the smallest known genomes (689 proteinencoding genes) (Himmelreich, Hilbert et al. 1996; Dandekar, Huynen et al. 2000), making it an ideal model organism for the investigation of absolute essentiality (Glass, Assad-Garcia et al. 2006). This analysis and the integration with other consistently derived large-scale datasets provide a blueprint of the proteome organization in a minimal cell and reveal principles underlying adaptation to a reduced genome. General principles of cellular organization in Mycoplasma pneumoniae 16 2.4. Materials and methods 2.4.1. Construction of a collection of M. pneumoniae strains expressing a TAP-fusion TAP-fusions were expressed in M. pneumoniae M129 (ATTC29342 broth passage No. 31) strains. Primers were designed for all 689 ORFs in M. pneumoniae. Each ORF was amplified by PCR using cosmid DNA as template (Wenzel and Herrmann 1988; Wenzel and Herrmann 1989). PCR products were digested (NotI/ SfiI) and ligated into the pMT85-based pMT_ClpBTAP-tag vector (Zimmerman and Herrmann 2005), which carries the Staphylococcus aureus transposon Tn4001 and the TAP cassette downstream of the SfiI site (Figure 2). Transformation of M. pneumoniae was done by electroporation, following published protocols (Hedreyda, Lee et al. 1993). Following transformation and recovery, cells were plated out in modified Hayflick medium (Hayflick 1965), containing gentamycin (78 mg/l) and incubated at 37ºC as described earlier (Catrein, Herrmann et al. 2005). Cell culture was tested for expression by Western blot with a Peroxidase-Anti- Peroxidase antibody developed in rabbit (Sigma, P1291).

TAP purification of protein complexes and mass spectrometric analysis Two-liter cultures were incubated in ten 300 cm2 cell culture flasks (Sarstedt) and harvested 96 h after inoculation. Cells were washed twice with ice cold PBS and centrifuged at 9,860xg. Pellets were resuspended in 2 ml lysis buffer (50 mM Tris pH 7.5, 5% glycerol, 1.5 mM MgCl2, 100 mM NaCl, 0.2% NP40, 1 mM DTT, 1 mM AEBSF, 1 mM PMSF, 1 μg/ml pepstatin A, 1 μg/ml antipain, 2 μg/ml aprotinin, 1 μg/ml leupeptin and 16 μg/ml benzamidin) and lysed mechanically using a douncer. TAP purification was done following established protocols (Rigaut, Shevchenko et al. 1999; Puig, Caspary et al. 2001). Protein samples were then analyzed by SDS-PAGE (4-12% NuPage, Invitrogen). Sample preparation for mass spectrometry was done essentially as described earlier (Shevchenko, Wilm et al. 1996; Gavin, Bosche et al. 2002). Briefly, whole gel lanes were cut into 32 equal slices; the proteins were then destained and digested (Trypsin, 12.5 mg/ml). Peptides were extracted in 1% formic acid in acetonitrile, resuspended in 0.1% TFA in water, mixed (1:1) with matrix solution (0.1% TFA in 50% acetonitrile and 50% methanol) and spotted on MALDI-TOF plates (Micromass, Waters). The MS analyses were carried out on a MALDI Micro MXTM (Waters, Milford, MA, USA). All data were acquired in positive ion mode over m/z range of 900-3,500 in reflectron mode. Peak masses were extracted from the spectra and used for protein identification (Supplementary CD). 2.4.3. Sample preparation for PeptideAtlas data collection M. pneumoniae M129 (ATTC29342 broth passage No. 31) strain cells were washed twice in ice cold PBS, harvested and pelleted by centrifugation at 9,860xg. Cells were resuspended in 100 µl denaturation buffer (100 mM ammoniumbicarbonate, 8 M urea, 0.1% RapiGest™(Waters)), sonicated for 5 minutes and spun down for 5 minutes at 20,000xg at 4ºC. A small aliquot of the supernatant was taken to determine the protein concentration using a commercially available BCA based protein assay kit (Pierce #23227). 2.4.4. Protein digestion for PeptideAtlas data collection The proteins were reduced with 5 mM TCEP for 60 minutes at 37°C and alkylated with 10 mM iodoacetamide for 30 minutes in the dark before diluting the sample with 100 mM ammoniumbicarbonate to a final urea concentration below 2 M. Proteins were digested by incubation with trypsin (1/50, w/w) overnight at 37°C. The peptides were cleaned up by C18 reversed-phase spin columns according to the manufacturer’s instructions (Harvard Apparatus). General principles of cellular organization in Mycoplasma pneumoniae 18 2.4.5. Directed mass spectrometry for PeptideAtlas data collection The setup of the μRPLC-MS system was as described previously (Schmidt, Gehlenborg et al. 2008). The hybrid LTQ-FT-ICR mass spectrometer was interfaced to a nanoelectrospray ion source (both Thermo Electron, Bremen, Germany) coupled online to a Tempo 1D-plus nanoLC (Applied Biosystems/MDS Sciex, Foster City, CA). Peptides were separated on a RP-LC column (75 μm x 15 cm) packed in-house with C18 resin (Magic C18 AQ 3 μm; Michrom BioResources, Auburn, CA, USA) using a linear gradient from 98% solvent A (98% water, 2% acetonitrile, 0.15% formic acid) and 2% solvent B (98% acetonitrile, 2% water, 0.15% formic acid) to 30% solvent B over 120 minutes at a flow rate of 0.3 μl/minutes. Each survey scan acquired in the ICR-cell at 100,000 FWHM was followed by MS/MS scans of the three most intense precursor ions in the linear ion trap with enabled dynamic exclusion for 30 seconds. Charge state screening was employed to select for ions with at least two charges and rejecting ions with undetermined charge state. The normalized collision energy was set to 32%, and one microscan was acquired for each spectrum. For directed LC-MS/MS, two data-dependent LC-MS/MS runs, the SuperHirn peak extraction and alignment algorithm (Mueller, Rinner et al. 2007) was used to extract all MS1 peaks. After removing all features for which MS2-data was obtained, the remaining 24,461 masses were divided in four lists and subsequently sequenced using directed LC-MS/MS analysis as recently specified (Schmidt, Gehlenborg et al. 2008). 2.4.5. Data processing and compilation of PeptideAtlas MS/MS spectra were searched using the SEQUEST search tool (Yates, Eng et al. 1995) against a decoy database (consisting of forward and reverse protein sequences) of the predicted proteome from M. pneumoniae strain M129 (ATTC29342), complete genome NCBI genome number NC_000912 (http://www.ncbi.nlm.nih.gov/entrez), consisting of 689 proteins as well as known contaminants such as porcine trypsin and human keratins (Non-Redundant Protein Database, National Cancer Institute Advanced Biomedical Computing Center, 2004, ftp://ftp.ncifcrf.gov/pub/nonredundant). The search was performed with semi-tryptic cleavage specificity, mass tolerance of 15 ppm, methionine oxidation as variable modification and cysteine carbamidomethylation as fixed modification. The database search results were further processed using the PeptideProphet program (Keller, Nesvizhskii et al. 2002) with decoy option. The peptide FDR was set to 1% (p=0.7). General principles of cellular organization in Mycoplasma pneumoniae 19 2.4.6. Peptide Mass Fingerprinting Mass intensity files were analyzed with MASCOT (Perkins, Pappin et al. 1999) and AlDente (Tuloup, Hernandez et al. 2003; Gasteiger, Hoogland et al. 2005) to identify proteins (Figure 3, A and B). Parameter settings were 80 ppm and 0 missed cleavages for both programs. For Aldente, shift was set at 0.20, slope at 200 and minimum number of peptides at two. For MASCOT, identifications above PMF score 45 were always taken and above 30 only if the consolidated score was at least 80 percent of the maximum consolidated score for that protein. For AlDente the same files were used for PMF against a random database. All identifications scoring lower than the random database were excluded. From these PMF identifications, proteins scoring higher than 1.5 were always taken and higher than 0.5 only if the consolidated score was at least 80 percent of the maximum consolidated score for that protein. 2.4.7. Reproducibility To assess the quality of the entire approach, we first measured the reproducibility of the overall experimental process, i.e. growth of adherent M. pneumoniae strains expressing TAPfusions, lysis of the cell pellets, TAP purification of protein complexes and mass spectrometric identification of protein complex components. For this purpose, we ran this entire procedure in duplicate for 18 strains expressing different TAP-fusions. We measure a reproducibility rate of 73% for proteins involved in the high confidence interactions, which are the ones that cluster in complexes in the dataset. This is comparable to most published studies, including that of Sowa et al. that recently reported 80% reproducibility (derived from four duplicated experiments) for high confidence interactions (Sowa, Bennett et al. 2009). We also more specifically assess the quality of the MS and protein identification strategy. For this purpose, 72 MS samples (see procedure above) were processed for MALDI-TOF analysis in duplicate; the reproducibility for protein identification is 97%. 2.4.8. Profilogs Proteins that have overlapping peptide mass profiles (we coined the term Profilogs) could lead to spurious identifications. To detect spurious identifications of this sort we use the results from the PeptideAtlas. The masses of sequenced peptides by FT-MS (PeptideAtlas) were entered into MASCOT and AlDente to identify proteins by PMF. False positives (Profilogs) are in this case identifications of proteins by PMF that were not the proteins sequenced in MS2 (PeptideAtlas). Mascot scores of false positive identifications (Profilogs) were recorded (Figure 3, C and D). For each protein identified by FT-MS, we identify all possible Profilogs as false positive identifications by PMF. In the PMF results of the TAP purifications, all General principles of cellular organization in Mycoplasma pneumoniae 20 identifications that were not the top-ranking proteins were considered as background if they are Profilogs and they were not further considered. Figure 3 Protein identification by MS. From all purifications, we processed 10,447 samples for MS. Proteins were identified using a refined approach that integrates both Mascot (Perkins, Pappin et al. 1999) and Aldente (Gasteiger, Hoogland et al. 2005) search algorithms. (A) This strategy increases the retrieval rate of true positives by 20% compared to only using Mascot. (B) The retrieval rate is calculated by comparing to known complexes. Of all the expected subunits that also belong to these known complexes, we retrieved 25%. The retrieval rate is used in the socio‐affinity scoring. (C) the PeptideAtlas was used to define profilogs; proteins that, in a MS experiment, give rise to overlapping peptide mass profiles. The masses of the sequenced peptides were used to do a PMF, if the actual sequenced protein is retrieved this is a true positive identification. If a different protein is retrieved this is a false positive identification resulting from the fact that the two proteins are profilogs. General principles of cellular organization in Mycoplasma pneumoniae 21 Black line: distribution of true positive identification scores. Red line: false positive identification scores. (D) Same as (C) however the Aldente scores are ordered to the maximum false positive score for each protein. In the screen, after using both Aldente and Mascot identifications to find significant proteins, the best‐scoring protein is always kept. Consecutive lower scoring hits are removed if a better‐scoring protein is a profilog of the lower scoring protein. 2.4.9. Consolidated scores MASCOT and AlDente scores of overlapping identifications were used to re-scale all the PMF scores, such that they have the same distribution. For PMF result, the maximum of the two rescaled scores was taken as the consolidated score. These consolidated scores were used in the subsequent analyses. Altogether, the set of successful redundant purifications comprises 259 purifications (Table S1) from 212 unique baits. In total 411 proteins were identified in the consolidated set of identified proteins (Table S1; Figure 4, A, B, C, D, E; and 5). General principles of cellular organization in Mycoplasma pneumoniae 22 General principles of cellular organization in Mycoplasma pneumoniae 23 Figure 4 Proteome coverage (functional & physicochemical). In (A) we represent the fraction of proteins identified per specified COG class (Tatusov, Koonin et al. 1997) in our TAP‐MS analysis (green), other proteomics analyses (Regula, Ueberle et al. 2000; Ueberle, Frank et al. 2002; Jaffe, Berg et al. 2004) including the PeptideAtlas (yellow), as well as those proteins predicted from the genome, but not yet observed (white). The M. pneumoniae genome contains 689 annotated protein coding genes, of which 564, corresponding to 82% of the genome, have been observed by MS‐based screens before our study. In the TAP‐MS analysis General principles of cellular organization in Mycoplasma pneumoniae 24 we detected 411 distinct M. pneumoniae proteins. Combining the results from the TAP‐MS screen, the PeptideAtlas as well as previous screens, a total of 622 proteins (90% of the genome) have been detected. (B) Virtual 2D gel where proteins are represented according to their size, y‐axis, and isoelectric point, x‐axis. The proteins identified in our dataset are colored red the ones not identified are seen in blue. The distribution of identified proteins covers molecular weights from 6 to 215 kDa and the pI range between 4 and 11.8. (C) The graph represents the fraction of proteins with a given molecular weight that were identified in the TAP‐MS analysis. MWs were extracted from UniProt. Proteins were grouped into different MW classes by exponential binning and subsequently counted. The plot shows that small proteins, e.g. below 20kDa, are significantly underrepresented (P = 0.000444). The R2 between the molecular weight and the fraction detected is 0.88 (correlation of 0.94). The table in panel (D) shows the five protein domains or motifs that were significantly underrepresented in the dataset. Proteins were classified according to their domain or motif composition according to SMART (Letunic, Doerks et al. 2009). The percentage of proteins with a given domain or a given motif that were identified in the TAP‐MS analysis was calculated. P‐values were calculated with the χ²‐test. (E) The graph represents the fraction of proteins with a given mRNA abundance that were identified in the TAP‐MS analysis. For abundance, we took the log2 signal of mRNA abundance on a spotted array measured under reference conditions and binned with a bin width of 0.5. Per bin, the number of proteins and the fraction detected was calculated. Low abundant proteins are underrepresented. There was no relation found between detection probability and hydrophobicity, when hydrophobicity scores were calculated using GRAVY. Figure 5 Screen saturation curve. The graph shows the cumulated number of non‐redundant proteins identified per TAP purifications as a function of increasing numbers of purifications performed. The 259 purifications are represented on the x‐axis in computationally randomized fashion, while the 411 identified proteins are depicted on the y‐axis. The average value, over ten randomization procedures, of proteins identified after a specific amount of purifications is shown in red. The maximal/minimal value, over ten randomization procedures, of proteins identified after a specific amount of purifications is shown in blue and yellow, respectively. General principles of cellular organization in Mycoplasma pneumoniae 25 2.4.10. Socio-affinity scoring and integration of quantitative prey profiling across the entire dataset The socio-affinity scoring was adapted from (Gavin, Aloy et al. 2006; Collins, Kemmeren et al. 2007). To further discriminate contaminants from cognate complexes components we also integrated systematic quantification of the preys across the entire dataset using spectral counting. Our approach is very similar to what has been reported by Sowa et al. (Sowa, Bennett et al. 2009) who originally integrated averaged spectral counts from technical duplicates to the interaction scores. Their datasets, focused on a limited set of purifications, contained only rare instances of reciprocal data (reverse tagging). In contrast, in genome-wide datasets run to saturation (Figure 5), reciprocal interactions are frequent. Thus, for each protein in the dataset, we could derive quantitative profiles across different purifications where proteins were present as bait or preys (Figure 6A). We ranked all interactions according to the quality of the MS data. This ranking is based on the PMF scores from MASCOT and AlDente, which explicitly take into account spectral counts, further normalized for length of the peptides and number of possible tryptic peptides per protein. Therefore, the PMF score represents a more accurate measure than spectral counts alone. More specifically, the approach is based on the principle that proteins present as contaminants in a given purification often have low PMF scores (i.e. they are less abundant and they are thus identified by a smaller number of peptides; they have lower spectral counts). Reciprocally, the presence of such contaminant proteins with a high PMF score in a given purification is usually indicative of a true interaction. Thus, we wanted to give a higher socioaffinity, if the PMF score was close to the maximum for that prey. We then sorted all identified preys by PMF score across different purifications (using different baits), and use the rank divided by the total number of times the prey was identified instead of the count divided by the background frequency. In this way, we ensure that preys when identified with a higher spectral count (reflected in the PMF score) receive a higher interaction score with this bait than when they are identified with a lower spectral count (usually indicative of spurious interactions). Socio-affinity (SA) is build up of the Spokes component (S) where direct bait-prey relations are counted and a Matrix component (M) where preys are counted that are seen together in a purification (equation 1). S is a summation over the scores (s) of all purifications (k) where the bait (i) was used and prey (j) was identified (equations 2 and 3) or prey (j) was not identified (equation 4). The retrieval rate (r) is estimated to be 0.25 and the probability (pijk) of finding a bait-prey interaction is estimated from a Poisson distribution (Collins, Kemmeren General principles of cellular organization in Mycoplasma pneumoniae 26 et al. 2007) where nikprey is the number of preys identified in purification k with bait i, nibait is the number of times protein i was used as bait, and fj is an estimate of the nonspecific frequency of occurrence of prey j in the dataset, where we took a value of 1 for npseudo. We computed fj as Bayesian posterior estimates based on the observed frequency of occurrence of preys in the dataset and the prior hypothesis that all preys occur non-specifically with equal frequency, for fj , we take only the prey frequency until the PMF score of the prey- identification with bait i (Figure 6A). Similarly, for the Matrix component (M), m was summed over all purifications where both prey (i) and prey (j) occur together. The value for pijk is calculated using the Poisson distribution as in equation 9 where fi and fj are computed as in equation 6, and ntotprey-prey is the total number of prey-prey pairs observed in the dataset. Equations: (1) SA = S ij + S ji + M ij (2) S ij = ∑ sijk k r + (1 − r ) pijk (3) s ijk = log10 (4) s ijk = log 10 (5) p ijk = 1 − exp(− f i f j ntotprey − prey ) pijk (1 − r )(1 − p ijk ) (1 − pijk ) = log 10 (1 − r ) n jpreyobs + n pseudo (6) fj = (7) M ijk = ∑ mijk ntotpreyobs + (n distinct preys n pseudo ) k r + (1 − r ) pijk (8) mijk = log10 (9) pijk = 1 − exp(− f i nikprey nibait ) pijk General principles of cellular organization in Mycoplasma pneumoniae 27 ∑P ∑P pc1 (10) MI = pc 2 N pc1 N pc 2 ∑ Pc1c 2 N c1c 2 Figure 6 Refined socio‐affinity scoring, benchmarking & clustering. (A) Example of PMF scores for a protein that appears either as contaminant or as cognate interactor in different purifications. On the x‐axis is the MASCOT score of all identifications of Mpn004. On the y‐ axis is the cumulative frequency of identifications of Mpn004. This protein seems to be a contaminant in many purifications (low score). However, if the bait was Mpn003 (a known interactor), Mpn004 (red arrow) is identified with a very high MASCOT score (many identified peptides). This was also the case for other interactors within known complexes. Therefore, in the spoke component of the socio‐affinity, we take for fj only the cumulative prey frequency until the PMF score of the prey‐identification with bait i. (B) The socio‐ affinity scoring was adjusted from (Gavin, Aloy et al. 2006; Collins, Kemmeren et al. 2007). For every identified prey we ranked the PMF scores. The rank is now used instead of the frequency of the prey in the socio‐affinity scoring of bait‐prey relations. On the x‐axis is the normalized, refined socio‐affinity. Accuracy was estimated for each bin of socio‐affinity scores. Accuracy was measured by the golden standard set of known complexes (Table S4). TPInts are interactions between proteins of the same complex, whereas FPInts are interactions between proteins of different complexes. Accuracy is TPInt/(TPInt+FPInt), dots. A logistic is done and the logistic curve was used to estimate for each protein‐pair, the probability of an interaction. (C) During clustering the number of proteins clustering in complexes as well as the size of the largest complex was monitored. We chose a threshold to General principles of cellular organization in Mycoplasma pneumoniae 28 define complexes such that many proteins are in complexes but still the size of the largest cluster has not exploded yet. This is depicted in c where on the x‐axis the number of proteins in complexes and on the y‐axis the number of proteins in the largest complex is shown. We chose a threshold that includes 348 proteins into the complexes of our analysis. (D) Nomenclature and definition: classification of protein complex components into cores (ellipses) and attachments (diamonds). 2.4.11. Socio-affinity score benchmarking A curated list of known complexes was inferred by homology to known complexes from the literature (Table S4). The interactions between proteins in the same complexes form the positive set. The interactions between proteins in different complexes form the negative set. Reported accuracies for function prediction are always lower boundaries as there could be true interactions also in the negative set. The protein-protein interactions were scored using socio-affinity and classified in the positive or negative set (Figure 6B). Then we performed a logistic regression on the socio-affinities and used the resulting logistic function to map the socio-affinities to interaction probabilities. 2.4.12. Integration with predicted interactions Predicted interactions were taken from STRING (COG mode) (Jensen, Kuhn et al. 2009); predictions from databases and text mining were not taken into account. For every protein pair, we now have an interaction probability from TAP and an interaction probability from STRING (Jensen, Kuhn et al. 2009). These two probabilities were integrated the same way as in STRING: P = 1- (1-p1)(1-p2). A weak score from TAP and a high score from STRING could indicate physical interactions (van Noort, Snel et al. 2007) without predicting other functional interactions. For the clustering into complexes only those protein pairs were taken that were seen together in purification at least once. From this we considered a set of 1,058 high confidence interactions for clustering into complexes (Table S2). 2.4.13. Clustering We adopted the clique percolation method from the CFinder method (Adamcsek, Palla et al. 2006). This is one of the clustering methods were proteins can belong to multiple complexes. We used k=3 to find cliques and used overlapping cliques to define the cores of the complexes. We took the high-confidence interactions (Table S2) and retrieved protein pairs that have each other as highest scoring interaction partner (stable pairs). If these stable pairs were part of a complex, they were also considered core members. If these stable pairs were not part of a complex, they were added to the complex list as complex of size two. To the core General principles of cellular organization in Mycoplasma pneumoniae 29 complexes, we added proteins with only one high-confidence interaction and call these attachment proteins. We used different cut-offs for interaction probabilities to define complexes and monitored the number of proteins clustering in complexes as well as the size of the largest complex. We chose a threshold to define complexes such that many proteins were in complexes but still the size of the largest cluster has not exploded yet (Figure 6C). Altogether the study reports 116 heteromultimeric protein complexes (Table S3). 2.4.14. Characterization of homomultimeric protein complexes The TAP-fusions were expressed from an exogenous locus and promoter. As a consequence the TAP-fusions were present together with their untagged wild type allele. It was not rare that in the same purification we could observe both TAP-tagged and untagged versions of the bait, indicating homomultimerization. We manually inspected the 1D SDS-PAGE gel and MS results for instances where the bait was present in more than one band. The bait was considered homomultimeric, if we identified it in two distinct bands corresponding to the MW of the tagged and the untagged versions. Altogether the study reports 62 homomultimeric protein complexes (Table S3). 2.4.15. Treatment of the extracts with RNase/DNase To digest DNA and RNA, some extracts were treated with RNase and DNase prior TAP. We added 3 µl of RNase (Roche) and 1 spatula tip of DNase (Roche) to a cellular pellet in lysis buffer before mechanical lysis with the douncer. TAP, SDS-PAGE and mass spectrometry were then performed as described above. The association between RpoA-TAP and the ribosome was unaffected by this DNA/RNA treatment indicating the interactions does not imply RNA or DNA (Figure 7 A and B). 2.4.16. Total RNA purification After growth, surface-attached cells are washed once with PBS at 37°C and immediately lysed in the cultivation flask by adding RLT buffer from the QiagenTM RNeasy Plus Mini Kit (Cat. Num. 74134). For cell lysis, 1.8 ml of RLT buffer in presence of 18 μl βmercaptoethanol was used per cultivation flask. RNA purification was done according to the manufacturer’s protocol. Purification of RNA in presence of RNase inhibitors is also shown in Figure 7A.

(B) RNA polymerase and ribosomal proteins copurify in various purifications. The matrix shows the different baits used in the top of each column and the preys identified by MS in each row underneath. This underlines ability to reversely purify the RNA polymerase with ribosomal entry points and vice versa. 2.4.17. Evaluating protein complexes by gel filtration chromatography and western blot GF chromatography was performed at 10°C on a Pharmacia SMART system at a flow rate of 40 µl/minute by using a SuperoseTM 6 PC 3.2/30 column, equilibrated with lysis buffer. The chromatographic profile was monitored at 280 nm by using the µPeak monitor (Pharmacia). Volumes of 50 µl of M. pneumoniae lysates were loaded on a column and 60 µl fractions were collected and analyzed by SDS-PAGE and Western blot (Figure 8B and 14A). A peroxidase anti-peroxidase antibody (Sigma, P1291) was used to detect the TAP-fusions (alpha subunit of DNA-directed RNA polymerase: RpoA-TAP and segregation and condensation protein A: ScpA-TAP). Polyclonal antibodies produced in rabbits have been used to detect the 30S ribosomal protein S4 (RpsD), the ATP-dependent protease La (Lon) and the protein P115 homolog (P115); final detection was done using secondary antibodies coupled to HRP (Sigma). For the quantification, total band intensity was integrated with Photoshop software (Adobe) and normalized versus the highest detected peak (Figure 14A).

N.D.: not determined. 2.4.18. Multifunctionality index For each set of two protein complexes and one protein, a multifunctionality index (MI) value was calculated (Table S6). This index reflects the tendency for the protein to be part of both complexes and corrects for the possibility that these two complexes should have been one complex, but was separated due to the chosen threshold. General principles of cellular organization in Mycoplasma pneumoniae 32 MI is calculated between each protein and each complex as above where the sums of the interaction scores (P) between the protein under consideration and the members of protein complex 1 (pc1) and protein complex 2 (pc2) are multiplied and divided by the product of the Number of members (N) in complex 1 and complex 2 (equation 10). This is divided by the sum over the interaction scores (Pc1c2) between members of complex 1 and complex 2 divided by the total number of protein pairs (N c1c2) between complex 1 and complex 2, not taking into account the protein for which the MI is being calculated (equation 10). To benchmark the results from the MI a curated list of known multifunctional proteins from the literature was used (Table S7). 2.4.19. Electron microscopy and image reconstruction of selected complexes Selected protein complexes (DNA gyrase, DNA topoisomerase, RNA polymerase) were purified according to the first step of the TAP-protocol (see above). The resulting TEV-eluate was further purified on a glycerol-gradient and fixed by cross-linking following the GRAFIX protocol (Kastner, Fischer et al. 2008). Fractions containing the bait were identified by dotblot using an antibody against calmodulin-binding domain. For electron microscopy, samples were prepared from fractions containing the bait by sandwich negative staining (Golas, Sander et al. 2003) (Figure 9). For DNA gyrase the first models were determined by random conical tilt reconstruction (Radermacher, Wagenknecht et al. 1987). The first model of the topoisomerase was determined by projection matching of class averages against the final map of the gyrase. For RNA polymerase a low-pass filtered map of the polymerase from Thermus aquaticus (1l9u) was used as first reference (Murakami, Masuda et al. 2002). Maps were further refined by iterative projection matching against the current best map using SPIDER (Frank, Radermacher et al. 1996). 2.4.20. Cultivation of M. pneumoniae strain B176 for electron tomography The M. pneumoniae B176 avirulent, noncytadsorbing strain that lacks the 40- and 90-kDa proteins, the products of the ORF6 gene (Mpn142), was used in this analysis (Ruland, Himmelreich et al. 1994). In comparison to its parental strain, the virulent M. pneumoniae M129, B176 does not grow in colonies and hence is more suitable to image individual cells by electron tomography of plunge-frozen samples.

Bottom row shows surface representations of the image reconstructions from the same direction as the projections above. The scale bars equal 10 nm. 2.4.21. Tilt series aquisition Single-axis tilt-series were collected covering an angular range from -66° to +66° with 1.5 degrees of angular increment in a Tecnai G2 Polara microscope cooled to liquid nitrogen temperature and equipped with a Gatan postcolumn GIF 2002 energy filter. Data acquisition was carried out under low-dose conditions using the UCSF tomography software (Zheng, Braunfeld et al. 2004). Images were recorded on a 2k x 2k pixel CCD camera at a defocus level between -5 and -10 μm. The pixel size at the specimen level was 0.6 nm. 2.4.22. Image processing The images were interactively aligned with respect to a common origin using 10 nm colloidal gold particles distributed in the sample as fiducial markers. The reconstructions were performed using weighted back-projection algorithm and visualized with the Amira package (Pruggnaller, Mayr et al. 2008). General principles of cellular organization in Mycoplasma pneumoniae 34 2.4.23. Mapping of complexes in cellular tomograms We scanned 26 tomograms of whole M. pneumoniae cells (with sub-pixel alignment error), with four templates: the ribosome (Gabashvili, Agrawal et al. 2000), GroEL (Forster, Pruggnaller et al. 2008), the RNA polymerase, and the structural core of the pyruvate dehydrogenase (PdhC, homomultimer) (Izard, Aevarsson et al. 1999), by means of locally normalized cross-correlation (Frangakis, Bohm et al. 2002). We have developed a classification method integrating knowledge on protein complexes networks for the detection of putative complexes inside cellular tomograms that largely overcomes the problem of template bias and significantly increases detection certainty (Figure 10). The principle here is that a tomogram is scanned with a template resembling an incomplete complex. The part of the complex, which is deliberately ignored, does not need to be structurally relevant. Complexes are identified as such, when the ignored part is recovered after the classification. Here, we illustrate the procedure on the example of the ribosome. The tomogram (Figure 10A) is scanned with a portion of the whole ribosome, in this case the large ribosomal subunit (50S). The resulting probability map (Figure 10B) contains only the probabilities that the large ribosomal subunit is located at particular positions in the electron tomogram. Most of the ribosomes will most probably have the small ribosomal subunit (the 30S) attached to the large one (Figure 10, C and D). Hence, when classifying the hits obtained for the 50S subunit, we expect to identify classes which show the ribosome as a complete entity. We expect that the sub-tomograms composing those classes will have significantly reduced false positive rates, since the additional density resembles the structure of the small ribosomal subunit increases our level of fidelity. On each cell, the locally normalized cross-correlation (Frangakis, Bohm et al. 2002) produced a list of putative particles, which were further classified using the missing wedge independent procedure (Pascual-Montano, Donate et al. 2001; Forster, Pruggnaller et al. 2008) with a network of 5x5 classification units (Figure 10E). Visual inspection of these classification units reveals the presence of extra-density which was not included in the original template. The similarity of this extra density to the 30S subunit is further asserted by normalized cross correlation and Fourier Shell Correlation. As an effective decision criterion is considered a high cross-correlation value and a Fourier Shell correlation extending into the higher frequencies. The sub-tomograms classifying in classification units with high Fourier Shell Correlation components are accounted as putative particles (Figure 10F). All other hits are rejected.

(E) In the green overlay contour the 50S is indicated and in the purple the 30S small ribosomal subunit. The overlays are also superimposed to the classification units. (E) Protein complex‐based classification strategy using the ribosome as an example. In our methodology, the 50S subunit is used to search through the whole tomogram (in six degrees of freedom, three rotational and three translational). Sub‐Tomograms at all local maxima of the cross‐correlation map are extracted and subjected to missing wedge independent classification with KerDenSOM. A cropped region of the total output map of KerDenSOM is shown. A projection image of five out of the 25 classification units is presented. In the first row the Fourier shell correlation, visualized as the blue plot in the bottom right corner of the images, is at the high frequencies indicating high similarity of the density inside the green overlay region to the small ribosomal subunit. The Fourier shell correlation curves of all the other classification units are either close to zeros (showing no similarity) or even negative similarity (due to the inverted contrast). The visual inspection confirms this result. Hence only the sub‐tomograms classifying within the classes on the upper row are selected in this example to contain true hits for the ribosomes. The number of hits assigned to each class appears in the upper‐left corner of the classification unit. (F) Isosurface representation of the whole M. pneumoniae cell with the putative complexes mapped inside. Membrane (blue) and tip organelle (green) can also be visualized. The color mapping of the complexes is as in (C). 2.4.24. Quantitative Western blotting To determine absolute quantities of GroEL and ribosomes in M. pneumoniae, levels of RpsD and the GroEL monomer were quantified by Western blotting. M. pneumoniae recombinant RpsD and GroEL genes used as standard were cloned into the pET19b vector, and proteins carrying an N-terminal poly-histidine tag were expressed and purified from E. coli cells. Protein concentrations were determined using a commercially available BCA based protein assay kit (Pierce #23227) essentially following the instructions in the product manual. Western blotting was carried out with polyclonal antibodies against RpsD and GroEL, respectively. Western blot bands were quantified using the software “ImageJ”. Relating band intensity values to known protein amounts of the purified standards and to the experimentally determined protein per M. pneumoniae cell ratio (10 fg/cell), allowed the calculation of copies of ribosomes and GroEL particles per cell, considering the homooligomeric state of the GroEL particle (Xu, Horwich et al. 1997) (Figure 11, A and B). The value for the quantified Western blot band is divided by the slope of the standard curve and multiplied by 1e-9 to obtain the amount of RpsD and GroEL in grams per gel lane. General principles of cellular organization in Mycoplasma pneumoniae 37 Figure 11 Quantitative Western blots of GroEL and ribosomal protein S4 (RpsD) in whole cell extract (A) Top panels: 0‐100 ng affinity purified GroEL and RpsD protein was loaded next to a M. pneumoniae cell lysate and blotted with polyclonal antibodies (Antibodies: R. Herrmann). Bottom panels: Standard curves from quantified Western blots. The slope of the trend line was used to determine the amount of GroEL and RpsD protein in a M. pneumoniae cell lysates (red square). The error in quantifying the amount of GroEL in the M. pneumoniae sample is 2.1%, as judged from five measurements and 6.6% for RpsD, as judged from four measurements. (B) Estimation of the number of molecules of GroEL and RpsD proteins in a M. pneumonia cell. Determination of the protein concentration of the M. pneumoniae cell lysate (5.07 g/l) and the amount of protein per M. pneumoniae cell (10 fg/cell) allows for calculating the number of cells per gel lane, considering dilution factors and the amount of lysate loaded. Dividing the amount of RpsD and GroEL per lane by the number of cells/lane gives a value for RpsD and GroEL in grams per cell. This number is then transformed to moles by dividing it with the molecular weight of the respective proteins in g/mol. The Avogadro constant determines 1 mol to contain 6.022e23 particles. Dividing the amount of protein per cell in moles by the Avogadro constant allows the determination of molecules per cell. Since GroEL is a General principles of cellular organization in Mycoplasma pneumoniae 38 homotetradecamer, this number has to be divided by 14 to obtain a number for GroEL particles in a single cell. RpsD is believed to be in a 1:1 stochiometry with ribosomes; hence the number of RpsD molecules directly reflects the number of ribosomes in a single M. pneumoniae cell (Figure 11B). 2.4.25. Structural bioinformatics Homologous proteins were collected using PSI-BLAST (Altschul, Madden et al. 1997) with default parameters. Hidden-Markov Models were built and used to find homologues of known structures from PDB (Berman, Henrick et al. 2003) using HHMake and HHSearch modules of the HHPred suite (Soding 2005). Matches of at least 50 residues in the query and with an Evalue ≤ 0.01 were considered further. Two matches were considered to be in physical contact when they did not overlap on the target sequence and each had at least 10 residues within 5.0 Å of the other. Overlaps between multiple interfaces on a single protein were calculated as the number of such residues that they had in common, and the interfaces clustered in to groups using these overlaps and the Markov Cluster algorithm ‘MCL’ (van Dongen 2000)(Table S5). General principles of cellular organization in Mycoplasma pneumoniae 39 2.5. Results 2.5.1. Genome-wide screen for protein complexes in M. pneumoniae We adapted the TAP-MS protocol (Rigaut, Shevchenko et al. 1999)to M. pneumoniae M129 (Figure 12). We processed all 689 M. pneumoniae protein-coding genes, of which 617 were successfully cloned (90% of the genome (Dandekar, Huynen et al. 2000)). Using a transposon-based expression system, we constructed a total of 456 M. pneumoniae strains. They carry a stable genomic integration of carboxy-terminal TAP-fusions under transcriptional control of the M. pneumoniae clpB (mpn531) promoter. From this collection, all 352 individual strains expressing soluble TAP-fusions were grown to confluence in two liters of adherent culture, leading to 212 successful purifications. The components of the purified complex were separated by denaturing gel electrophoresis, and individual bands trypsin-digested and analyzed by MS (Supplementary CD). We processed a total of 10,447 MS samples and identified proteins using a new approach that integrates the Mascot (Perkins, Pappin et al. 1999) and Aldente (Gasteiger, Hoogland et al. 2005) search algorithms (Resing, Meyer-Arendt et al. 2004). This increased the identification of known complex component by ~20% compared to either method alone (Figure 3, A and B). The procedure also scores the quality of individual identifications considering all peptide profiles we observed for each protein, including our purification dataset and a PeptideAtlas, a comprehensive set of tryptic peptides (Desiere, Deutsch et al. 2006) measured with Fourier transform-MS from whole M. pneumoniae lysates (Supplementary CD). We removed protein identifications with overlapping peptide profiles (3%) (Figure 3, C and D). When applied to the entire purification dataset, this approach uncovered 411 distinct proteins from 5,899 identifications (Table S1). General principles of cellular organization in Mycoplasma pneumoniae 40 Figure 12 Synopsis of the genome‐wide screen of complexes in M. pneumoniae. The 411 proteins identified with 212 tagged proteins correspond to 60% of the annotated ORFs and 85% of the predicted soluble proteome (Figure 4). They cover all cellular functions, though low abundant, small or trans-membrane segment-containing proteins are significantly underrepresented (Figure 4). Membrane proteins purification requires separate biochemical protocols so they were not included in this screen. The proportion of new proteins identified per purification dropped asymptotically as the screen progressed, implying that the procedure was near saturation (Figure 5). This entails recurring protein complex retrieval through reverse tagging, and is important both to confirm novel interactions and to identify dynamic complexes (Gavin, Aloy et al. 2006). To define complexes in a quantitative way, we first calculated socio-affinity indices that measure the frequency with which pairs of proteins were found associated in our set of biochemical purifications (Gavin, Aloy et al. 2006). We improved the concept by integrating predicted interactions from the STRING database (Jensen, Kuhn et al. 2009) and the relative abundance of a given prey when associated with different baits (i.e. across different purifications (Sowa, Bennett et al. 2009)). We used the MS scores that measure the probability for a peptide mass fingerprint to characterize each protein based on spectral counting. A reduced score for a prey in a purification, when compared to the same prey in other purifications, reflects identifications by a smaller number of peptides (lower spectral counts) and is indicative of a spurious interaction; is therefore down-weighted (Figure 6A). We applied this new scoring scheme to the entire dataset and calculated a list of 10,083 General principles of cellular organization in Mycoplasma pneumoniae 41 interactions. A cut-off was defined at an accuracy, i.e. fraction of true interactions (von Mering, Krause et al. 2002), of more than 80%, which gave a set of 1,058 high-confidence interactions (Figure 6, B and C; see also Table S2). We also measured the overall experimental reproducibility on a set of 18 experiments that we performed twice; duplicates included growth of adherent cultures, biochemical purifications and MS analyses. For protein pairs with socio-affinity scores ≥ 0.8 the overall reproducibility is 73%; for those scoring below it is 43% (P = 10-13, χ² test). For comparison, the reproducibility calculated on the duplicated MS measurements of 72 MS samples is 97%. We then applied cluster analysis, using a procedure called clique percolation that allows proteins to be part to different complexes. We varied the clustering parameters over reasonable ranges. The best conditions in terms of coverage (see below) generated a collection of 116 heteromultimeric complexes. They are organized into densely (> one link) and loosely interconnected (one link) components we called “core” and “attachment”, respectively (Figure 6D and Table S3). Generally, M. pneumoniae proteins within complexes and cores are more often co-expressed (Guell, van Noort et al. 2009) and conserved between species than average; protein within complexes appear on average in 244 species compared to 173 for the entire proteome (median = 190). Comparison to a set of 31 known complexes, described in other species (Table S4), revealed a coverage of 61%, which is similar to results from previous screens in yeast and E. coli (coverage ~60%) (Gavin, Bosche et al. 2002; Butland, Peregrin-Alvarez et al. 2005; Gavin, Aloy et al. 2006; Krogan, Cagney et al. 2006). 2.5.2. Systematic detection of homomultimeric protein complexes The TAP-fusions were expressed from exogenous loci and promoter and are therefore present together with the untagged wild-type allele. It was thus common to observe both TAP-tagged and untagged versions of the bait in the same purification, which is an indication of homomultimerization (Figure 7). Careful scrutiny of the purification dataset revealed evidence for 62 homomultimeric complexes (Table S3) covering 62% of those previously seen either in M. pneumoniae or in another species by orthology (Table S4). Fourteen homomultimeric complexes were novel, and for 12 of these we could find supporting structural evidence from homologs of known structure (Berman, Henrick et al. 2003) (Table S5). An example is Mpn266, a protein of previously unknown function that we found associated to RNA polymerase (Complex 49; Table S3) as a dimer. Its binding to the polymerase is consistent with its similarity to SpxA, an RNA polymerase-binding protein that regulates transcription initiation in gram-positive bacteria (Zuber 2004; Yus, Maier et al. General principles of cellular organization in Mycoplasma pneumoniae 42 2009). Comparative modeling of structure and single particle electron microscopy (Figure 8A) (Guell, van Noort et al. 2009) show M. pneumoniae RNA-polymerase resembles that of Thermus aquaticus (Murakami, Masuda et al. 2002) with the exception of a substantially bigger stalk at the position of the sigma factor, RpoD (Mpn352), consistent with M. pneumoniae RpoD being 200 amino acids longer than its T. aquaticus ortholog (Figure 8A). The models also further support the idea that each Mpn266 in the dimer binds one of the two alpha subunits of the polymerase as do other transcription factors (Figure 8A). From the number of baits used (212) and from the effectiveness of the method in recovering known complexes (62% coverage), we estimate that as many as 47% of all soluble proteins form homomultimers in M. pneumoniae. This is in agreement with a recent analysis of more than 5,000 protein structures (Levy, Boeri Erba et al. 2008). Finally, considering both homo- and heteromultimers, almost 90% of soluble proteins were found to be part of at least one complex, a figure similar to values estimated in yeast (Gavin, Aloy et al. 2006; Krogan, Cagney et al. 2006). This further consolidates the view that exhaustive organization into complexes is a general property of proteomes in bacteria and eukaryotes. 2.5.3. Characteristics of M. pneumoniae protein complexes Overall, more than half of the identified complexes were not previously described. We also found new components in previously known complexes: the dataset contains 126 proteins with previously unknown or conflicting functional annotation. For example, complex membership identifies Mpn426, previously annotated as a P115 homolog, as the missing Smc (structural maintenance of chromosomes) DNA-binding subunit of the cohesin-like complex (Complex 40; Figure 8B and Table S3) (Yus, Maier et al. 2009). This complex also contains the ATP-dependent protease Lon (Mpn332) that binds DNA and regulates chromosome replication (Wright, Stephens et al. 1996). The observed physical association between Lon and Smc and the observation that Lon expression increases concomitant with Smc degradation at the onset of the stationary phase (Figure 8B) suggest Smc might be a target of this protease. The existence of a native complex including Lon, ScpA (Mpn300) and P115 is further supported by the observation that these three proteins co-elute during gel filtration chromatography (Figure 8B) (Yus, Maier et al. 2009). We also identified known eukaryotic complexes such as those including several GEs that have been discovered at eukaryotic plasma membrane, where they locally produce ATP (Table S4). We observed similar assemblies in M. pneumoniae (Complexes 12 and 45; Table S3) suggesting that this function is conserved in bacteria. General principles of cellular organization in Mycoplasma pneumoniae 43 2.5.4. Comparison of methods for estimation of proteome organization We overlaid the protein complex data with complementary large-scale datasets that have been previously used to deduce physical interactions (Figure 13A). Only 48% of the TAP interactions within complexes were found in any existing dataset; 359 associations were only identified by TAP-MS (Figure 13A). Even in the worst-case scenario, where we consider the upper limit of the estimated false-positives rate (20% = 100%-80% accuracy) and assume that false positives are completely excluded from the other datasets, we estimate at least 220 new true associations were identified here. Overlap with interactions inferred from genome organization or gene expression was particularly low: only 7% of the high confidence interactions are between gene products from the same operon and only 18% were consistently co-expressed (Guell, van Noort et al. 2009). This implies that temporal or conditional regulation of complex formation is analogous to that for eukaryotes, in which different components are expressed at different times (de Lichtenberg, Jensen et al. 2005). For example, the four known subunits of the RNA polymerase are in three operons and their transcription profiles correlate with two different gene expression groups along the growth curve (Guell, van Noort et al. 2009; Yus, Maier et al. 2009). With current knowledge, only a small fraction of proteome organization can be inferred from analysis of the genomes or transcriptional data making proteomics studies critical for understanding prokaryotic systems. General principles of cellular organization in Mycoplasma pneumoniae 44 Figure 13 Proteome organization is only partially reflected by other biological datasets. (A) General overlap between TAP and interactions inferred from other datasets: co‐expression, operons (Guell, van Noort et al. 2009; Yus, Maier et al. 2009), STRING (Jensen, Kuhn et al. 2009) and pathways (Kanehisa, Araki et al. 2008). Numbers refer to the interacting pairs within the different datasets. The fraction of TAP‐interactions that cluster into complexes and are covered by other datasets is given in between brackets. For TAP interacting protein pairs the cut‐off was set at 80% accuracy. Cut offs for other datasets were optimized for coverage (accuracies 40 to 100%). (B) Frequent functional cross‐talk in the protein complex dataset. All proteins within high confidence pairs were functionally annotated according to COG (Tatusov, Koonin et al. 1997). Boxed areas are colored proportionally to the number of interactions linking two functional classes. The scales represent the total (upper panel) and normalized (lower panel) number of interactions (von Mering, Krause et al. 2002). Category Q (secondary metabolites) contains only two proteins. The category most frequently linked is J (Translation) with itself; it however contains the highest number of proteins. The highest proportion of interactions is between proteins within category K (Transcription). General principles of cellular organization in Mycoplasma pneumoniae 45 2.5.5. The M. pneumoniae protein complex network reveals substantial cross-talk About a third of the heteromultimeric complexes in M. pneumoniae have extensive physical interconnections that suggest proteins participate in different cellular processes (Figure 13B). These reflect protein multifunctionality (see below) and organization into at least 35 larger assemblies, sometimes hinting at physical, possibly temporal associations of sequential steps in biological processes (Table S3). For example, we reconstituted major parts of the ribosome from the interaction screen and saw extensive cross-talk with RNA polymerase (Figure 14A). This higher level association was unaffected by RNAse and DNAse treatments suggesting protein-protein rather than protein-nucleic acid interactions were involved (Figure 7). The TAP-MS data were consistent with gel filtration results showing the RNA polymerase alphasubunit, RpoA (Mpn191), and the ribosomal protein RpsD (Mpn446) co-elute with high apparent molecular sizes (Figure 14A). These observations are further supported by the genome organization, where the rpoA gene is localized in and co-regulated with a ribosomal operon (Guell, van Noort et al. 2009). This network provides a molecular model for the coupling of transcription and translation proposed in bacteria (Gowrishankar and Harinarayanan 2004) and the direct involvement of ribosomal proteins in transcriptional regulation (Torres, Condon et al. 2001). The same assembly also includes translational initiation factors InfA (Mpn187), InfB (Mpn155) and InfC (Mpn115), which are part of the 30S initiation complex, as well as elongation factors Tuf (Mpn665) and Tsf (Mpn631), suggesting that we have captured sequential steps in a pathway running from transcription to translation. 2.5.6. Functional reuse and modularity of protein complexes Genome-wide screens in eukaryotes show that proteins often participate in more than one complex, an attribute that has been proposed to account for protein multifunctionality, pleiotropy or moonlighting (Hodgkin 1998). We defined a multifunctionality index that measures the tendency of proteins to associate with more than one complex. This is based on frequency with which pairs of proteins were found associated in our set of purifications and is insensitive to the clustering parameters. We found 156 multifunctional proteins (Table S6), covering 54% of M. pneumoniae proteins that are currently known to be multifunctional in the literature (Table S7). We also compared to a set of multifunctional enzymes that catalyze different enzymatic reactions (Yus, Maier et al. 2009) and the overlap was smaller (32%). Our analysis captured distinct mechanisms for multifunctionality that imply the combinatorial use of gene products in different contexts, for different functions. General principles of cellular organization in Mycoplasma pneumoniae 46 Figure 14 Higher level of proteome organization. (A) The RNA polymerase‐ribosome assembly. Core components are represented by circles, attachments by diamonds. The line attribute corresponds to socio‐affinity indices: dashed lines, 0.5–0.86; plain lines, > 0.86. Color code and shaded yellow circles around groups of proteins refer to individual complexes: RNA polymerase (pink), ribosome (purple) and translation elongation factor (green). The lower panel shows the ribosomal protein RpsD (23kDa) and the α subunit of the RNA polymerase, RpoA‐TAP (57kDa) co‐elute in high molecular weight fractions (MDa range) during gel filtration chromatography. (B) DNA topoisomerase (diameter ~12 nm) is a heterodimer in bacteria: ParE, (ATPase and DNA‐binding domains), and ParC (cleavage and C‐terminal domains). The interaction between ParE‐DNA‐binding and ParC‐cleavage domains was modeled using yeast topoisomerase II as a template (PDB code 2rgr) and ParE‐ATPase and ParC C‐terminal domains were modeled separately on structures of gyrase homologs (1kij & 1suu). All four domains were fitted into the EM density. Gyrase (~12 nm) is similarly split in bacteria, into GyrA/GyrB, which are paralogs of ParE/ParC, and was modeled and fitted using 1bjt as a template for the GyrB‐DNA‐binding and GyrA‐cleavage domains interaction. (C) Protein multifunctionality in M. pneumoniae illustrated with the aminoacyl‐ tRNA synthetase complexes. For example, GyrA (Mpn004) is a component of the DNA gyrase complex that introduces negative supercoils into DNA, and ParE (Mpn122), is a member of the topoisomerase IV complex which decatenates DNA (Zechiedrich and Cozzarelli 1995). Besides well documented interactions within their respective complexes (Complexes 17 and 82; Table S3), GyrA and ParE were also found to stably associate with each other (Complex 102; Table S3). Single particle electron microscopy and comparative modeling (Figure 8 and General principles of cellular organization in Mycoplasma pneumoniae 47 9) showed that DNA-topoisomerase and DNA-gyrase have related overall shapes, as expected from their functional similarity, and also supports the notion that they might be able to interchange subunits (Figure 14B). In eukaryotes ParE and ParC (Mpn123) are fused into one single polypeptide. In bacteria, the possibility for the split ParE and ParC to contribute to different complexes might represent a parsimonious way of generating functional diversity and also robustness to mutations with a set of paralogous proteins. Another example is a complex containing a cluster of five different AARSs (Complex 10; Figure 14C and Table S3). In eukaryotes and archaea, AARSs form macromolecular complexes that improve aminoacylation efficiency by channeling substrates to ribosome (Praetorius-Ibba, Hausmann et al. 2007; Kyriacou and Deutscher 2008). These assemblies also act as reservoirs of AARSs that additionally exert a range of non-canonical regulatory functions in transcription, metabolism and signaling (Park, Schimmel et al. 2008). The existence in bacteria of big multi-AARS complexes is controversial; the most recent review advocates assembly in binary complexes that are functionally involved in tRNA metabolism and editing (Hausmann and Ibba 2008). Our results suggest that higher order multi-AARS complexes might also exist in bacteria. We also found several AARSs in other complexes involved in functions as diverse as translation, transcription, DNA replication, and metabolism (Figure 14C). 2.5.7. Structural anatomy of M. pneumoniae Because of their small genome size, bacteria from the genus Mycoplasma have attracted attention as model organisms for structural genomics (Kim, Shin et al. 2005). We used these data to populate our protein complex network with structural information. Sequence similarity searches and comparative modeling provided structures for 484 M. pneumoniae proteins (70% of the genome), and 340 proteins in the network. There were also structural templates to construct models for 153 binary interactions (Figure 12) covering 29 heteromultimeric and 57 homomultimeric complexes (Table S5). These data can be used both to study particular interactions or complexes (Figure 14B and 8A) and to infer general correlations. Structural interfaces are particularly illuminating for the multifunctional proteins. When structural models are available for multiple interactions with a common protein, analysis of the interfaces can suggest whether the interactions are mutually exclusive (same binding sites), or compatible (different sites) (Kim, Lu et al. 2006). We observed that multifunctional proteins generally tend to accommodate more ligands per interacting interface (P = 0.003), consistent with the view that multifunctionality engages mutually exclusive interactions. For example, General principles of cellular organization in Mycoplasma pneumoniae 48 the protein P115 (Mpn426) has six distinct interfaces, each of which has several mutually exclusive interaction partners. Figure 15 From proteomics to the cell. By a combination of pattern recognition and classification algorithms the following TAP‐identified complexes from M. pneumoniae, matching to existing EM, X‐ray and tomogram structures (A), were placed in a whole‐cell tomogram (B): the structural core of pyruvate dehydrogenase in blue (~23 nm), the ribosome in yellow (~26 nm), RNA polymerase in purple (~17 nm), and GroEL homomultimer in red (~20 nm). Cell dimensions are ~300 nm by 700 nm. The cell‐membrane is shown in light‐blue. The rod, a prominent structure filling the space of the tip region is depicted in green. Its major structural elements are HMW2 (Mpn310) in the core and HMW3 (Mpn452) in the periphery stabilizing the rod (Seybert, Herrmann et al. 2006). The individual complexes (A) are not to scale, but they are shown to scale within the bacterial cell (B). Having assembled a repertoire of structural information, the next logical step is to map these networks and protein complexes in their native environment, the cell. For this purpose, we performed cryo-electron tomography of 26 entire M. pneumoniae cells (Seybert, Herrmann et al. 2006) (Figure 10). We used pattern recognition techniques to generate General principles of cellular organization in Mycoplasma pneumoniae 49 probability maps for complexes selected from the larger ones in M. pneumoniae (Figure 15), as they are more likely to be identified. After a thorough classification considering missing data, low signal-to-noise ratio and known spatial proximities of different sub-complexes we generated maps for the ribosome, the chaperone GroEL (Mpn573), the structural core of the pyruvate dehydrogenase (PdhC, Mpn391, homomultimer), and RNA polymerase, with a minimal number of false positives (Figure 15). These large complexes are excluded from the tip, an organelle required for the attachment to epithelial cells, illustrating that even in a simple, minimal bacteria the proteome is spatially organized (Seybert, Herrmann et al. 2006). Within the cell bodies, we could not find significant proximities or patterns among the different complexes. In contrast to E. coli that contain a compact nucleoid forming an exclusion area in the cell center (Thanbichler and Shapiro 2008), circular DNA in M. pneumoniae is apparently uniformly distributed (Seto, Layh-Schmitt et al. 2001). We estimated the average number of complexes per cell to 140 for the ribosome, 100 for GroELs, 100 for pyruvate dehydrogenase and 300 for RNA polymerase. For the ribosome and GroEL, we also quantified complex abundances by Western blotting (Figure 11). For both, the numbers derived from Western blot were in the range of those estimated from the tomograms. This adds to the emerging view that the mapping of macromolecular structures into entire cell tomograms (Al-Amoudi, Diez et al. 2007), even though still challenging, is a powerful strategy when combined with unbiased large-scale complex purification. It opens the way to more general charting of cellular networks in entire cell tomograms. 2.6. Conclusions Our genome-scale screen for soluble complexes in a bacterium provides a valuable resource for the functional annotation of many genes whose biological roles in prokaryotic or parasitic cells are elusive. The coverage of known complexes leads to an estimate of some 200 molecular machines in M. pneumoniae. The study allows estimation of unanticipated proteome complexity for an apparently minimal organism that could not be directly inferred from its genome composition and organization or from extensive transcriptional analysis. Organisms with small genomes are the most tractable for systems biology, and the biochemical dataset, proteome-wide spectra, ORFome and collection of TAP-expressing M. pneumoniae strains will provide an extremely useful resource for this community. Comparison to both more complex bacteria and to even smaller ones, such as M. genitalium with 485 annotated protein coding genes (Gibson, Benders et al. 2008), should reveal additional systemic features associated with genome streamlining. General principles of cellular organization in Mycoplasma pneumoniae 50 With protein structures available for about three quarter of its ORFs, either directly from structural genomics efforts (Kim, Shin et al. 2005) or indirectly inferred by homology, M. pneumoniae has been extensively studied. We demonstrated that we can integrate datasets of biochemically determined complexes with structural information to approximate the threedimensional organization of proteins into functional molecular machines. These models can then be mapped in entire cell tomograms, providing a three-dimensional view of cellular proteomes and interactomes (Bork and Serrano 2005); ultimately whole cell models will benefit studies of biological function and disease.

Authorship This chapter covers the systematic investigation of the metabolism and its regulation in M. pneumoniae. It represents a minor part of work during my time as a predoctoral fellow at EMBL Heidelberg and ETH Zürich. This study has a first authorship by Eva Yus, who performed the minimal medium experiments, contributed to the reconstructed the metabolic network, generated expression data, did major parts of the cell culture work and majorly contributed editing manuscript and figures. Additionally there are numerous other co-authors who had their unique contributions. My main contributions were providing comparative data and reagents from the proteome analysis and participating in cell culture work. Additionally, I prepared and edited figures as well as the manuscript of this study. This chapter represents a reformatted version of a report that has been published in Science. 3.2. Abstract To understand basic principles of bacterial metabolism organization and regulation, but also the impact of genome-size thereon, we systematically studied one of the smallest bacteria, Mycoplasma pneumoniae. A manually curated metabolic network of 189 reactions catalyzed by 129 enzymes allowed the design of a defined, minimal medium with 19 essential nutrients. More than 1,300 growth curves were recorded in the presence of various nutrient concentrations. Measurements of biomass indicators, metabolites and 13 C-glucose provided information on directionality, fluxes and energetics; integration with transcription profiling enabled global analysis of metabolic regulation. Compared to more complex bacteria, the M. pneumoniae metabolic network has a more linear topology and contains a higher fraction of multifunctional enzymes; general features such as metabolite concentrations, cellular energetics, adaptability and global gene expression responses are similar though. General principles of cellular organization in Mycoplasma pneumoniae 52 3.3. Introduction Accurate representation of cellular networks by mathematical models is a central goal of integrative systems biology. For this purpose, all components and reactions of a target system should be listed and validated, and their quantitative relations should be determined and analyzed in the context of the physiology of the organism (Feist and Palsson 2008). We have selected M. pneumoniae, a human pathogen causing atypical pneumonia (Waites and Talkington 2004) as a model organism for bacterial and archebacterial systems biology. Like other mollicutes, M. pneumoniae has undergone a massive genome reduction to include only 689 protein coding genes, 231 of which have unknown function (Supplementary CD Yus et al. Table S1) (Dandekar, Huynen et al. 2000); yet it can be cultivated in vitro without helper cells (Proft and Herrmann 1994). The genome reduction of M. pneumoniae favors its suitability as a systems biology model because it largely follows genome size scaling principles (Supplementary CD Yus et al. Figure S1) (van Nimwegen 2003). We manually reconstructed and validated the metabolic network of M. pneumoniae and studied its regulation, thereby complementing analyses of the transcriptome (Guell, van Noort et al. 2009) and the proteome organization (Kuhner, van Noort et al. 2009). 3.4. Results 3.4.1 Reconstruction of the metabolic network: verification by a defined, minimal medium The metabolism of M. pneumoniae has been studied biochemically (Pollack 1997) and computationally (Pachkov, Dandekar et al. 2007). We integrated these approaches in a framework that maximized coverage and accuracy (Supplementary CD Yus et al.). To build a comprehensive metabolic network, we complemented the reactions from KEGG (www.genome.jp/kegg) with activities obtained manually from the literature and new annotations (Supplementary CD Yus et al. e.g. in Tables S1 to S5 and Figure S2) (Pollack, Williams et al. 1997). We also considered other genomic (co-occurance in one operon), sequence (homology to known enzymes) and structural information (identification of catalytic residues to ensure enzyme functionality) (Figure 16A and Supplementary CD Yus et al. Figure S2 and S3). For example, we identified an incomplete ascorbate pathway by sequence analyses and filled the gap by assigning a critical enzyme (L-ascorbate-6-phosphate lactonase, mpn497) based on sequence homology, predicted activity (metal-dependent hydrolase) and its position in the ascorbate operon (mpn492 to 497). For pathways where only one enzyme was General principles of cellular organization in Mycoplasma pneumoniae 53 missing we closed the gap by adding an unassigned reaction (e.g. transketolase activity in the pentose pathway). Putative enzymes missing conserved catalytic residues were discarded (e.g. Mpn255 and Mpn673 enzymes of the terpenoid pathway). Finally, for enzymes that could carry out more than one reaction, we removed the reactions that were decoupled from pathways and those for which the substrate was unavailable. The final result was a map without gaps, isolated reactions, or open metabolic loops (Figure 17). A number of alternative pathways interactions between pathways as well as missing enzymes still needed to be validated, and reaction directionalities had to be inferred. For this, we used two different experimental strategies. We first used the rich medium (Supplementary CD Yus et al. Figure S4) to validate the pathway functionality in various carbon sources. As expected from the map (Figure 17), all known carbon sources but mannitol supported growth to various extents (Supplementary CD Yus et al. Figure S5 and S6) (Halbedel, Hames et al. 2004). By using 13 C-glucose labeling we validated, for examples, the predicted connection between glycolysis, the pentose phosphate pathway and lipid synthesis (Supplementary CD Yus et al. Figure S3 and Table S6), and ruled out the proposed production of aspartate from pyruvate (Manolukas, Barile et al. 1988). For our second strategy we developed, based on the metabolic map, a defined medium (Figure 16A and Supplementary CD Yus et al. Table S7) with which we could validate other pathways (e.g. vitamin metabolism, Supplementary CD Yus et al. Figure S10) and reaction directionalities that could not be studied in rich medium (e.g. synthesis of uracyl and thymine nucleotides from cytosine; Supplementary CD Yus et al. Figure S7 and S8). The low number of amino acid permeases and transporters and the existence of a peptide importer (oppB-F cluster, Table S1) suggested a requirement for peptides in the medium, which we confirmed experimentally (Supplementary CD Yus et al. Figure S9). General principles of cellular organization in Mycoplasma pneumoniae 54 Figure 16 Metabolic network development and properties, and minimal medium design. (A) Schematic diagram of the process leading to M. pneumoniae metabolic network reconstruction and design of a minimal medium. (B) Comparison of M. pneumoniae metabolic network properties with the ones of other model bacteria, (C) quantification of enzyme multifuntionality among prokaryotic genomes: M. pneumoniae (red), L. lactis (yellow), B. subtilis (green) and E. coli (blue), other bacterial species (grey). We systematically tested the defined medium in more than 1,300 experiments to properly assess all the components necessary for survival. We replaced these components with simpler building blocks to obtain a defined, minimal medium that contains only 26 components (19 of which are essential; Figure 16A). This medium, as predicted from our metabolic map and comparative analysis also supports growth of Mycoplasma genitalium (Supplementary CD Yus et al. Figure S11 and S12). Based on these experiments we estimated the upper flux limits for the utilization of the various nutrients (Supplementary CD Yus et al. Figure S13). The medium implicitly validates the reconstructed metabolic map (Figure 17) which consists of 189 reactions (Supplementary CD Yus et al. Table S2): 169 are catalyzed by the products of 140 known genes, and 20 are not yet assigned to any gene (Supplementary CD Yus et al. Table S4). It includes 74 essential metabolic genes and 34 conditionally essential ones (depending on medium composition), which is in agreement with essentiality determined by transposon mutagenesis analyses (96% overlap; Supplementary CD Yus et al. Figure S14 and Table S8) (Hutchison, Peterson et al. 1999). A total of 32 enzymes (25%) are multifunctional, i.e. have more than one activity and together catalyze 91 reactions (48% of the total; Supplementary CD Yus et al. Table S3). With respect to previous genome annotations (Himmelreich, Hilbert et al. 1996; Dandekar, Huynen et al. 2000), we assigned new or refined functions to 57 metabolic genes (plus 30 non-metabolic genes, Supplementary CD Yus et al. see new annotations in Table S1). The above strategy could more generally be used to design General principles of cellular organization in Mycoplasma pneumoniae 55 media to grow anexically, hard-to-culture bacteria as was done for the recalcitrant Tropheryma whipplei (Renesto, Crapoulet et al. 2003) and might be applicable in the context of increasing metagenomics efforts. 3.4.2. Comparison of the metabolic network to those of more complex bacteria Analysis of the metabolism of M. pneumoniae reveals that it is more linear than that of larger bacteria such as B. subtilis (Figure 16B). Furthermore, M. pneumoniae has a wider metabolic network diameter (shortest biochemical pathway averaged over all pairs of substrates) although the diameter has been reported to increase with the logarithm of the network size (Zientz, Dandekar et al. 2004). The greater linearity and the wider diameter of the network suggest that it is less interconnected and contains fewer parallel paths. Thus, the M. pneumoniae network is less redundant both in terms of enzyme paralogy and in network topology. Yet, the distribution of the number of metabolites per reaction is similar to other organisms (Supplementary CD Yus et al. Figure S14). This is partly achieved by an increased fraction of multifunctional enzymes compared to that in larger bacteria, as happens in endosymbionts (Zientz, Dandekar et al. 2004). We did not find any evidence of M. pneumoniae multifunctional enzymes being more conserved than others. This suggests the larger number could be due to function acquisition not present (or detected) in their homologs. This might represent a more general mechanism expected to facilitate further genome reduction (Figure 16B and C). The increased linearity and limited redundancy in the metabolic network suggest limited robustness and adaptability to external factors (Pipe and Grimson 2008): 60% of the metabolic enzymes are essential (Glass, Assad-Garcia et al. 2006), in contrast to only 15% in E. coli (www.shigen.nig.ac.jp/ecoli/pec/index.jsp).

Growth and energetics in comparison with larger bacteria. M. pneumoniae has a relatively long duplication time (at least 8 hours) in comparison with E. coli or L. lactis (20 min), both in culture (Hasselbring, Jordan et al. 2006) and in the presence of host cells (Dallo and Baseman 2000). Slow growth in genome-reduced, parasitic bacteria has been proposed to be the result of i) less efficient enzymatic activity that is explained by the accumulation of mutations resulting from genetic drift (Smart and Thomas 1987), ii) a reduced number of rRNA operons and/or iii) other mechanisms related to the adaptation to a parasitic lifestyle. To understand the causes of slow growth it is necessary to measure the overall energetics of the metabolic network (Figure 17), as well as the changes in macromolecules (Figure 18A) and metabolites along the growth curve (Figure 18B). We used the metabolic map, the measured protein concentration (10 fg protein per cell) and the estimated turnover rates of macromolecules (~20 hours for proteins and ~7 min for mRNA; Supplementary CD Yus et al. Table S9 and Figure S15) to estimate the rate of glucose uptake required to duplicate a cell every 8 h at 18,000-24,000 glucose molecules per second (assuming that the majority of ATP is used for biomass production) (Supplementary CD Yus et al.). This figure closely matched the experimentally determined value under exponential growth: ~19,000 glucose molecules per cell per second (Figure 18C) (Supplementary CD Yus et al.). When cultures approached stationary phase (Figure 18A), the rate increased to ~45,000 glucose molecules per cell per second (Figure 18C), concomitantly with the increased transcription of many glycolytic and fermentation genes (Figure 18D and Supplementary CD Yus et al. Table S10 and S11). In both cases at least 95% of the glucose carbon was found in lactate and acetate (Figure 18B and Supplementary CD Yus et al. Figure S16), implying that the glucose is used primarily for energy production. At the fastest glucose consumption rate, assuming all ATP were devoted to biomass production, M. pneumoniae could divide about every 3 hours. However, most of the energetic parameters (i.e. concentration of glycolytic intermediates: fructose-1,6-biphosphate, glycerol-3-phosphate, phosphoenolpyruvate, glucose-6-phosphate, fructose-6-phosphate, ribose-5-phosphate and glycerone phosphate, and glucose uptake) that we measured were similar to those of larger bacteria (Supplementary CD Yus et al. Table S9), suggesting comparable enzyme efficiencies. This similarity extended to regulatory processes seen in L. lactis (Moran 2002). General principles of cellular organization in Mycoplasma pneumoniae 58 For example, as in L. lactis, we observe both a shift from mostly mixed-acid to homolactic fermentation and an acceleration of glycolysis when the medium acidifies (Figure 18A and B); the drop in O2 concentration relieves inhibition of lactate dehydrogenase (Supplementary CD Yus et al.) (Smart and Thomas 1987; Cocaign-Bousquet, Even et al. 2002). Also, the ATP yield per fermented glucose (2 to 4 ATP, depending of lactate or acetate fermentation), is the same as in L. lactis (Supplementary CD Yus et al. Table S9). Figure 18 Determination of various metabolic parameters in growing cultures. Consistently generated heterogeneous data, all derived using a rich medium, are compared using time in hours (X‐axis). (A) M. pneumoniae growth determined by monitoring the decrease in extracellular pH and the concomitant changes in the amount of protein, DNA and total RNA. (B) Determination of glucose consumption and its fermentation to lactate and acetate. (C) Changes in the number of glucose molecules imported by a cell per second and comparison with the biomass doubling time. (D) Changes in gene expression of a representative ribosomal protein (rplX), and two enzymes: ldh, and a component of the pyruvate dehydrogenase complex (pdhA), enzymes from the two fermentation branches and the relation with the shift from acetate to lactate production (ratio between acetate and lactate General principles of cellular organization in Mycoplasma pneumoniae 59 is shown in green, which can be compared to that of cells grown in the presence of oxygen in magenta). Given all the above we cannot explain the slow growth of M. pneumoniae on the basis of glycolytic efficiency or ATP yield. One of the main differences compared to fast dividing bacteria is the number of rRNA operons per genome (just one in M. pneumoniae and 6 in L. lactis) (Supplementary CD Yus et al. Figure S17); and 5 to 10 times proportionally fewer ribosomes compared to E. coli (Supplementary CD Yus et al. Table S10) (Kuhner, van Noort et al. 2009). In many bacteria the number of ribosomes correlates with the division rate (Nomura 1999). For M. pneumoniae, we see a correlation of changes in biomass duplication speed with the number of ribosomes, but not with the glycolytic rate (Figure 18C and D and Supplementary CD Yus et al. Figure S17). We thus suggest that the slow division rate of M. pneumoniae is not due to less efficient energy production but to the limit in protein biosynthesis capacity. This small parasitic bacterium does not appear to be optimized for biomass production. Instead, more complex strategies for fitness, such as suppression of growth by other microorganisms (Teusink, Wiersma et al. 2006) or optimization of interactions with host-cells might determine growth-rate in small organisms. 3.4.4. Coordinated transcriptome dynamics along growth curve and under various conditions It has been suggested that genome-reduced organisms have limited adaptability to external factors (Cocaign-Bousquet, Even et al. 2002). To determine the capacity of M. pneumoniae to respond to environmental changes we performed three types of experiments. First, we followed the changes in gene expression from the exponential growth phase to the stationary phase (Figure 19A). Analysis of changes in gene expression (validated by tiling arrays and quantitative PCR; Supplementary CD Yus et al. Figure S18) at different points along the growth curve showed that a large part of the transcriptome can be grouped into four timedependent expression clusters (Figure 19A and Supplementary CD Yus et al. Figure. S19 and S20, Table S11 and S12). These clusters can be regarded as two pairs of anti-correlating patterns, indicating a complex regulation. Subsequent analysis by mass spectrometry for a subset of enzymes showed correlation between changes in mRNA and protein abundance (Supplementary CD Yus et al. Figure S18 and Table S10). For example, the production of lactate by lactate dehydrogenase (Mpn674|Ldh) revealed the close temporal coordination of General principles of cellular organization in Mycoplasma pneumoniae 60 gene and protein expression, and metabolite turnover (Figure 18B and D and Supplementary CD Yus et al. Table S10). Second, we analyzed the response of M. pneumoniae to specific individual metabolic perturbations encountered as the population grows, such as low pH, accumulation of fermentation end-products, and sugar and amino acid starvation, as well as to more complex stimuli like entry into the stationary phase (Figure 19 B to D and Supplementary CD Yus et al. Tables S13 to S16),. We found coordinated changes in gene expression specific to each condition (Figure 19B and Supplementary CD Yus et al. Figure S21). For example, we see a general inhibition of transcription and translation upon glucose deprivation, and an increase of ATP proton pump genes at pH 6.5 (Figure 19B and C). Induction of the stringent response (a global response to the absence of amino acids) results in upregulation of peptide and amino acid transporters (Figure 19D). Also a specific repression of the Thr-tRNA synthetase gene (mpn553) (Supplementary CD Yus et al. Table S17), which is a core component of a tRNA synthetase complex (Kuhner, van Noort et al. 2009), suggests its possible regulatory role in complex assembly and therefore, in regulation of translation. Interestingly, we found some common responses to multiple stresses. Some were known as was the down-regulation of ribosomal proteins or peptide importers, common to all stresses. Others, like the up-regulation of ldh and glycerol-3-P dehydrogenase (mpn051), were unexpected suggesting additional functions for these proteins during stress (Figure 19B). Third, we adapted the cells by serial passage (15 passages) to efficient growth in other carbon sources (fructose, mannose, and glycerol) (Supplementary CD Yus et al. Tables S18 to S20). Fructose adaptation resulted in over-expression of fruA and fruK (>3 Log2), and mannose-adapted cells over-expressed the mannitol importer (>5 Log2) (Supplementary CD Yus et al. Tables S19 and S20). Thus M. pneumoniae shows surprising adaptation capability similar to that reported for E. coli (Oxman, Alon et al. 2008). The coordinated changes in gene expression along the growth curve, the specific responses to many various metabolic perturbations and the adaptability of the cells to various carbon sources indicate that M. pneumoniae retains some robustness and adaptability despite its extreme genome reduction.

Complex metabolic regulation despite few transcription factors Compared to more complex bacteria, M. pneumoniae lacks the majority of TFs regulating metabolic genes factors (such as the CRP), major sigma factors and other regulators (Goebel and Lory 2006). Gene assignment based on sequence analysis (Supplementary CD Yus et al. Table S1), in some cases validated by co-purification with the RNA polymerase complex (e.g. mpn266|spxA) (Kuhner, van Noort et al. 2009), revealed four transcription factors (mpn239|gntR; mpn329|fur; mpn124|hrcA), the general sigma 70 (mpn352|sigA) factor, two putative sigma-like factors (mpn626|sigD; mpn424|ylxM) and a putative DNA-binding protein (mpn241|whiA) (see Supplementary CD Yus et al. Table S1 and Figure S2). Despite this apparently reduced gene regulatory toolbox, both environmental stresses (Guell, van Noort et al. 2009) and metabolic insults induced complex, specific transcriptional responses; comparison with more complex bacteria showed similarities, but also some specific differences in regulation of gene expression (Supplementary CD Yus et al. Table S21 to S23). For example, we observed an increase in mRNA and protein expression of glycolytic enzymes concomitant with the increase of glycolytic rate upon medium acidification (Figure 18C and D and Supplementary CD Yus et al. Figure S20 and Table S15), very similar to what has been described in L. lactis cultures (Even, Lindley et al. 2003). Response to glucose starvation was also similar to that of L. lactis (Figure 19C and E and Supplementary CD Yus et al. Table S21) (Even, Lindley et al. 2002). Part of the stringent response, e.g. induction of peptide and amino acid transporters and down-regulation of carbohydrate catabolism (Potrykus and Cashel 2008), was conserved in M. pneumoniae (Supplementary CD Yus et al. Table S22); other mechanisms such as the repression of ribosomal protein operons or rRNA synthesis were not observed (Figure 19D and Supplementary CD Yus et al. Figure S22). This is in agreement with the proposed involvement of the RNA polymerase omega subunit (missing in M. pneumoniae) in sensing guanosine pentaphosphate/tetraphosphate [(p)ppGpp] and thus arresting rRNA biosynthesis (Vrentas, Gaal et al. 2005). We believe it is unlikely that the conserved responses, and the specific differences in regulation, can be caused only by combinations of the few TFs that regulate operons and suboperons, even if one includes regulation by antisense RNA (Guell, van Noort et al. 2009). The presence of genes for synthesis or degradation of a number of chemical messengers, such as (p)ppGpp (mpn397|spoT), AppppA (mpn273|hit1), or c-di-AMP (mpn244|disA) General principles of cellular organization in Mycoplasma pneumoniae 63 (Supplementary CD Yus et al. see Table S1 and Figure S2) (Su, Hutchison et al. 2007), implies that signaling mechanisms has been preserved despite genome reduction. For example, over-expression of the spoT gene that regulates (p)ppGpp levels (Potrykus and Cashel 2008) results in significant changes in gene expression, mainly related to the stringent response (Supplementary CD Yus et al. Table S24). The presence of genes coding for a Ser/Thr phosphatase (mpn247|ptc1) and two protein kinases (Ser/Thr/Tyr kinase: mpn248|prkC, mpn223|hrpK, an HPr kinase) and the differential phosphorylation of key metabolic enzymes under various growth conditions (Su, Hutchison et al. 2007) suggest posttranslational control. Also metabolites like glycerol regulate gene expression at the base of the fermentation branches in M. pneumoniae (Halbedel, Eilers et al. 2007), as well as glucose import (Halbedel, Hames et al. 2007). This explains why glycerol is essential in the minimal medium in a concentration-independent manner (Figure 19F). 3.5. Conclusions Our results suggest that complex metabolic regulation can be achieved in a streamlined genome despite the absence of the respective TFs, probably by a combination of transcriptional regulators, post-translational modifications and small molecules including chemical messengers and metabolites. Taken together, our newly established M. pneumoniae resource, containing a manually annotated metabolic map, full annotations, reactome, consistently measured growth curves and gene expression profiles corresponding to an extensive list of metabolites, should facilitate integrative systems biology studies at a high resolution. Comparison to more complex bacteria revealed systemic features associated with genome streamlining, which should be examined in other small bacteria. Despite its apparently simplicity, we have shown that M. pneumoniae shows metabolic responses and adaptation similar to more complex bacteria, providing hints that other, unknown regulatory mechanisms might exist.

Abstract To study basic principles of transcriptome organization in bacteria, we analyzed one of the smallest self-replicating organisms, Mycoplasma pneumoniae. We combined strand-specific tiling arrays, complemented by transcriptome sequencing, with more than 252 spotted arrays. We detected 117 previously un-described, mostly non-coding transcripts, 89 of them in antisense configuration to known genes. We identified 341 operons, of which 139 are polycistronic; almost half of the latter show decaying expression in a staircase-like manner. Under various conditions, operons could be divided into 447 smaller transcriptional units, resulting in many alternative transcripts. Frequent antisense transcripts, alternative transcripts, and multiple regulators per gene imply a highly dynamic transcriptome, more similar to that of eukaryotes than previously thought. General principles of cellular organization in Mycoplasma pneumoniae 65 4.3. Introduction Although large-scale gene expression studies have been reported for various bacteria (Selinger, Cheung et al. 2000; Tjaden, Saxena et al. 2002; Reppas, Wade et al. 2006; McGrath, Lee et al. 2007; Nelson, Herron et al. 2008; Akama, Suzuki et al. 2009; ToledoArana, Dussurget et al. 2009), comprehensive strand-specific data sets are still missing, limiting our understanding of operon structure and regulation. Similarly, the number of classified non-coding RNAs in bacteria has recently been expanded (Vogel and Wagner 2007), but a complete and unbiased repertoire is still not available. To obtain a blueprint of bacterial transcription, we combined the robustness and versatility of spotted arrays (62 independent conditions and 252 array experiments) (Supplementary CD Güell et al.), the superior resolution of strand specific tiling arrays (Figure 20A) (designed after genome resequencing, Supplementary CD Güell et al. Table S1) and the mapping capacity of RNA deep sequencing (DSSS) (Fig 20A and Supplementary CD Güell et al. Figure S1) in one of the smallest bacteria that can live outside a host cell, M. pneumoniae, with annotated 689 protein coding genes and 44 non coding RNAs (ncRNAs). 4.4. Results Considering DSSS under reference conditions (Supplementary CD Güell et al.) and 43 tiling arrays from four time series (growth-curve, heat shock, DNA damage and cell cycle arrest) (Supplementary CD Güell et al. Table S8), we observed the expression of all genes. Using a segmentation algorithm for the tiling arrays (Huber, Toedling et al. 2006), we identified additional 117 regions with no previous annotation (Supplementary CD Güell et al. Table S2). These regions were further confirmed by DSSS (Figure 20B and Supplementary CD Güell et al. Figure S1) and in four cases by quantitative polymerase chain reaction (Supplementary CD Güell et al. Table S3). Sequence similarity with known proteins revealed the presence of two new protein-coding genes, a pseudogene, one N-terminal truncation, and five 5’-extensions of known genes (Supplementary CD Güell et al. Table S2). The remaining 108 transcripts are probably regulatory rather than structural RNAs, because comparison of their predicted secondary structures with the ones of coding genes does not show any substantial difference (Supplementary CD Güell et al.). Eighty-nine of them are antisense with respect to previously annotated genes. Out of the non-overlapping ones, two of them (NEW87 and NEW8) are General principles of cellular organization in Mycoplasma pneumoniae 66 conserved in M. genitalium and could be involved in DNA replication and repair, and in peptide transport, respectively (Supplementary CD Güell et al. Figure S3 to S5). In total, 13% of the coding genes are covered by antisense; this is twice more than in yeast (7%) (Xu, Wei et al. 2009), and about half of what was reported for plants (22.2%) (Wang, Gaasterland et al. 2005; Henz, Cumbie et al. 2007), or humans (22.6%) (Ge, Wu et al. 2006). Antisense transcripts may affect expression of the overlapping functional sense transcripts through several mechanisms (Lapidot and Pilpel 2006): double-stranded RNA-dependent mechanisms require coexpression with their target (Brantl and Wagner 1994), whereas transcriptional interference rather implies mutual exclusion of sense and antisense transcripts (Brantl 2007; Andre, Even et al. 2008). In M. pneumoniae, we observed a predominance of double-stranded RNA mechanism as in mammals (Katayama, Tomaru et al. 2005) (47% positive correlation versus 2% negative correlation). In addition, we detected a reduced expression level of genes targeted by antisense transcripts, as reported in some prokaryotes (Brantl 2007) (Supplementary CD Güell et al. Figure S6). Figure 20 Transcriptome feature in the reference condition. (A) The first operon in the genome on the forward strand has a staircase behavior, meaning that the consecutive genes have lower and steady expression levels. (B) Example of an anti‐sense RNA transcript. (C) Analysis of staircase operons. Left: all reference operons subdivided by the number of protein coding genes they contain. Right: all reference operons subdivided by their staircase behavior (see bottom graphs).

Right, Overlap of operon ends and single gene ends with predicted transcription termination hairpins. General principles of cellular organization in Mycoplasma pneumoniae 67 We identified operon boundaries through sharp transcription changes in the tiling reference condition by using local convolution methods (Figure 20A) (Supplementary CD Güell et al.) (Hooper, Boue et al. 2007). More than 90% of the operons (139 polycistronic and 202 monocistronic operons; Supplementary CD Güell et al. Table S4) were well supported by DSSS reads (DSSS alone was not sufficient to unambiguously characterize operons; Supplementary CD Güell et al. Figure S2). Most polycistronic operons contain two or three genes (Figure 20C and Supplementary CD Güell et al. Figure S7, Table S4); the largest one is the ribosomal operon containing 20 genes. For the majority of operons, we observed a canonical or slightly altered version of a standard sigma 70 promoter region (Supplementary CD Güell et al. Figure S8), with transcription starts located within 60 bp (Supplementary CD Güell et al. Figure S9) upstream of the translation start (McGrath, Lee et al. 2007). In contrast to previous suggestions (Washio, Sasayama et al. 1998), we observe, as proposed by others (de Hoon, Makita et al. 2005), a preferential use of termination hairpins for tight regulation of gene expression (Figure 20A and D and Supplementary CD Güell et al. Table S5). Moreover, we found that almost half of the consecutive genes within polycistronic operons show a decay behaviour (Figure 20A and Supplementary CD Güell et al. Figure S1), indicating that such ‘staircase’-like expression is a widespread phenomenon in bacteria (Supplementary CD Güell et al.). Analysis of the 43 tiling arrays and integration with 252 spotted arrays representing 173 independent conditions, some of them from time-series, revealed context-dependent modulation of operon structures involving repression or activation of operon internal genes, as well as of genes located at the beginning, or end (Figure 21A and B and Supplementary CD Güell et al. Figure S10 and Table S5). In some cases this modulation can be assigned to specific environmental changes. Down regulation of the four first genes of the ftsZ operon involved in initiation of cell division corresponds to entry into stationary phase (Figure 21B, lower panel). Increase in expression of arginine fermentation genes (arcA, arcI, arcC) (Figure 21B) in stationary phase could be a mechanism to cope with acidification (Budin-Verneuila, Maguin et al. 2004). We found formal evidence for a total of 447 transcriptional units (336 monocistronic and 111 polycistronic), implying a high rate of alternative transcripts (42%) in this bacterium in the conditions studied, similar to that in eukaryotes (40%, although still under debate) (Boue, Letunic et al. 2003) and archea (40% in H. salinarum) (Koide, Reiss et al. 2009). Interestingly we found that genes that are split into different suboperons tend to belong to different functional categories (Supplementary CD Güell et al.). Thus, although General principles of cellular organization in Mycoplasma pneumoniae 68 genome reduction leads to longer operons accommodating genes with different functions (Yus, Maier et al. 2009), the latter can still retain internal transcription and termination sites under certain conditions. The high frequency of alternative transcripts of M. pneumoniae genes hints at a situation similar to that in eukaryotes where many factors contribute to the regulation of gene expression. To further support this hypothesis, we used gene expression clustering under the 62 distinct conditions (Supplementary CD Güell et al. Table S7) to identify groups of coexpressed genes and their possible common regulatory motifs. Using a correlation cut-off of 0.65 we identified 94 co-expression groups (Supplementary CD Güell et al. Table S6 and Figure S11), encompassing 416 genes. Thirty of the clusters contained genes from more than two operons. Of these, 14 share a unique sequence motif in their upstream region and another 8 have a unique combination of motifs (Supplementary CD Güell et al. Figure S12), which might drive the co-expression (e.g. 4 of the 14 motifs are found at splitting sites inside operons). This is exemplified by the five heat shock induced genes containing a regulatory CIRCE element (Chang, Chen et al. 2008) (Figure 21C). Not all of them clustered together indicating at least another regulatory element. Similarly, over expression of a transcription factor (mpn329; Fur, ferric uptake regulator) reveals a common motif in all genes significantly changing expression, although they belong to different co expression clusters (Supplementary CD Güell et al. Figure S13 and Table S6). General principles of cellular organization in Mycoplasma pneumoniae 69 Figure 21 Alternative operon structure.

Conclusions Our work revealed an unanticipated complexity in the transcriptome of a genomereduced bacterium. This complexity cannot be explained by the presence of 8 predicted TFs (Yus, Maier et al. 2009). Furthermore, the fact that the proteome organization is not explainable by the genome organization (Kuhner, van Noort et al. 2009) indicates the existence of other regulatory processes. The surprisingly frequent expression heterogeneity within operons, the change of operon structures leading to alternative transcripts in response to environmental perturbations and the frequency of antisense RNA which might explain some of these expression changes suggest that transcriptional regulation in bacteria resemble that of eukaryotes more than previously thought. General principles of cellular organization in Mycoplasma pneumoniae 71 5. Summary of results The systematic investigation of cellular organization on different levels and the integration of this acquired information into other orthogonal datasets can leverage the creation of biological knowledge. This was one of the main tasks and is one of the major results of this thesis, which aims at describing general principles of cellular organization in the genome-reduced bacterium M. pneumoniae. Altogether there are three major studies described in this thesis which aim at the characterization of the: 1. proteome organization, 2. metabolism and its regulation, 3. transcriptome and its complexity in M. pneumoniae. In chapter 2, I describe the results of the investigation of the proteome organization in M. pneumoniae. The analysis revealed 62 homomultimeric and 116 heteromultimeric soluble protein complexes, of which the majority are novel. About a third of the heteromultimeric complexes show higher levels of proteome organization, including assembly into larger, multi-protein complex entities, suggesting sequential steps in biological processes, and extensive sharing of components implying protein multifunctionality. Incorporation of structural models for 484 proteins, single particle EM and cellular electron tomograms provided supporting structural details for this proteome organization. The dataset provides a blueprint of the minimal cellular machinery required for life. Chapter 3 outlines the results of the investigation of the metabolism and its regulation in M. pneumoniae. In order to understand basic principles of its metabolic organization and regulation, but also the impact of genome-size thereon a manually curated metabolic network of 189 reactions catalyzed by 129 enzymes was created. This allowed the design of a defined, minimal medium with 19 essential nutrients. More than 1,300 growth curves were recorded in the presence of various nutrient concentrations. Measurements of biomass indicators, metabolites and 13 C-glucose provided information on directionality, fluxes and energetics. The integration of transcriptional profiles enabled global analysis of metabolic regulation. Compared to more complex bacteria, the M. pneumoniae metabolic network has a more linear topology and contains a higher fraction of multifunctional enzymes; general features such as metabolite concentrations, cellular energetics, adaptability and global gene expression responses are similar though. General principles of cellular organization in Mycoplasma pneumoniae 72 Chapter 4 highlights the results of the investigation of the transcriptome complexity in M. pneumoniae. Here, we combined strand-specific tiling arrays, complemented by transcriptome sequencing, with more than 252 spotted arrays. We detected 117 previously un-described, mostly non-coding transcripts, 89 of them in antisense configuration to known genes. We identified 341 operons, of which 139 are polycistronic; almost half of the latter show decaying expression in a staircase-like manner. Under various conditions, operons could be divided into 447 smaller transcriptional units, resulting in many alternative transcripts. Frequent antisense transcripts, alternative transcripts, and multiple regulators per gene imply a highly dynamic transcriptome, more similar to that of eukaryotes than previously thought. In a more conceptual summary there are four major messages, which the three studies, of which my PhD thesis is part of, have produced: 1. M. pneumoniae shows aspects of multifunctionality particularly in its proteome organization and metabolism. 2. M. pneumoniae, even though being an almost minimal organism, is more complex than expected, particularly in its regulation. 3. M. pneumoniae resembles eukaryotes more than expected, particularly in its transcription. 4. M. pneumoniae is optimized for host adaptation and not for growth. General principles of cellular organization in Mycoplasma pneumoniae 73 6. Conclusions The work on the proteome organization, the metabolism and its regulation as well as on the transcriptional complexity in M. pneumoniae provided in this thesis adds to previous research and will certainly strengthen the interest in this genome-reduced organism (Ochman and Raghavan 2009). Furthermore, it will help to establish M. pneumoniae as a near-minimal model organism (Glass, Hutchison et al. 2009). As such this work will provide a useful ground for further systematic biological investigations in M. pneumoniae as well as related species and maybe even for its use in synthetic biology (Marshall 2009). In the following paragraphs I will therefore briefly express my personal view on i) the next possible directions of research in M. pneumoniae, ii) medically relevant aspects to be addressed, iii) necessary steps to make M. pneumoniae a candidate for biotechnological use as well as iv) possible biotechnological and synthetic biological applications of minimal cells. There are various scientific challenges and next steps of systematic research in M. pneumoniae focusing again on the basic understanding of this organism. In analogy to work performed in Leptospira interrogans useful insights could be derived from measuring proteome-wide cellular protein concentrations in M. pneumoniae as well as half-life of proteins and RNA (Malmstrom, Beck et al. 2009). In the best case scenario this would be performed investigating various relevant growth conditions. Similarly the protein interactions should also be charted in various conditions and along different stages of the cell cycle of M. pneumoniae. Along these lines it is also essential to get a better understanding of the global use of PTMs in these near-minimal cells. Currently only two types of protein cleavage, protein phosphorylation as well as protein acetylation are reported while others remain to be discovered (Herrmann and Ruppert 2006). Another rather neglected aspect is the membrane biology in M. pneumoniae and here especially the membrane proteome, which currently consists of about 100 proteins many of which are only vaguely annotated. At this end comprehensive mapping of the membrane proteome would further advance the understanding of M. pneumoniae. In addition to that the topology of all membrane proteins should also be looked at. Experiments using MS/MS analysis for membrane protein identification could be validated by orthogonal approaches e.g. immunogold labelling of membrane proteins and detection via EM, which could moreover add spatial information on the distribution patterns of membrane proteins. The relative or even absolute quantification via heavy isotope labelling would yet add another level of detail and could also help assess false positive hits from a nonGeneral principles of cellular organization in Mycoplasma pneumoniae 74 quantitative mapping approach. Finally the combination of these results and the integration of additional datasets like the ones provided in this thesis could help elucidate regulatory patterns of the extracellular membrane proteome in single- or multi-conditional analysis. Eventually these combined datasets could then be used for entire cell modelling in order to better understand the M. pneumoniae lifestyle and growth behaviour. From a therapeutic point of view an intensified investigation of the growth on host cells and a more thorough understanding of the pathogenicity of M. pneumoniae are the most urgent questions. Although numerous advanced have been made in the last 25 years in the elucidation of the attachment process and the proteins as well as oligosaccharides involved (chapters 1.1.1 & 1.1.2.) there still many regulatory details not understood. These ask for an in detail investigation of the attachment process to host cells as well as its regulation and a more systematic charting of the host-pathogen interaction network. Inhibitors with antibacterial function could be derived from exhaustive insights into the involved target molecules at various stages of the attachment process. These could be M. pneumoniae specific or in a best case scenario also amenable for other pathogens with a similarly regulated host cell recognition process. In order to make M. pneumoniae available for biotechnological applications there are a few limitations to tackle (chapter 1.1.3). Among them is the rather long generation time of 8h which severely slows down the growth potential of this pathogen and probably reflects its adaptive lifestyle to the host, which should not be killed. Trying to accelerate the M. pneumoniae generation time to 2h or less via genetic modifications seems a necessary prerequisite for industrial use. To that end it also seems required to use a non-adherent M. pneumoniae M129 strain like, e.g. B169/176 (Lipman, Clyde et al. 1969). This strain comes with the advantage of being able to grow in a three-dimensional fashion batch mode so that the biomass production can be increased. Additionally this strain appears to be avirulent and could possibly be reclassified to S1 security level, which would dramatically decrease the growth costs for a weight unit of cells. Another aspect that needs to be addressed is the growth medium. In this thesis a minimal medium for M. pneumoniae growth has been proposed (Yus, Maier et al. 2009). It seems worthwhile to check whether the defined minimal medium or the defined non-minimal medium are optimal also for long term batch culture growth of a modified bacterium that has the desired growth characteristics. From a genetic manipulation point of view the above proposed modifications seem to be achievable, especially considering the progress that has been accomplished by the synthetic biology & General principles of cellular organization in Mycoplasma pneumoniae 75 bioenergy group at the J. Craig Venter Institute (see chapter 1.1.3. for details) (Lartigue, Glass et al. 2007; Gibson, Benders et al. 2008; Lartigue, Vashee et al. 2009). Finally a short glimpse at potential applications for a controllable minimal organism in biotechnology and synthetic biology as reviewed (Serrano 2007). Such an organism could be used as a source for growing initial compounds for chemical synthesis, which are either impossible to produce in a chemical way or their chemical synthesis is simply uneconomic. Feasibility of such an approach was e.g. demonstrated for the production of terpenoid compounds in E. coli and S. cerevisiae, which have been used as precursors in the synthesis of antimalarial drugs (Martin, Pitera et al. 2003; Lindahl, Olsson et al. 2006; Ro, Paradise et al. 2006; Serrano 2007). Controllable minimal cells could also be exploited as a source for energy supply and research towards that aim appears to accelerate (Marshall 2009). Even more than for pure chemical synthesis, controllable cellular systems seem to be predestined for the production of a wide range of biologics, a market that is still growing according to a recent analysis (Aggarwal 2009). The above discussed points clearly show that there are still many questions of M. pneumoniae biology unanswered. Therefore future projects will help to further understand this nearminimal organism. The exact social benefit for the support of academic research towards that direction cannot be exactly estimated; however the odds are not too long that further investigations turn out to be extremely valuable.

Acknowledgements To say “Thank you” to many great individuals who helped me in one way or another over the past few years and in some cases life-long is not a compulsory task here but is something I do with the greatest pleasure and gratitude towards all my supporters, friends and family. First and most important for the successful completion of my PhD thesis I want to thank my supervisor at EMBL Heidelberg Dr. Anne-Claude Gavin, who was always extremely motivated, incredibly supportive and a great person to work with. I want to thank you AnneClaude for the great time I had in the lab, the invaluable lessons I learned form you as well as the great degrees of freedom I had during my work and the confidence you always had and have in our fascinating projects. Secondly, I would like to thank Prof. Dr. Ruedi Aebersold for giving me the opportunity and the support to perform my PhD thesis as an external PhD student in his laboratory at ETH Zürich and for the reliably great input during our meetings. I am especially thankful to you Ruedi for the very warm welcome in Zürich and all your open mindedness that I will also always forward in life. In order to perform a lot of high quality work it is of priceless to be in a lab with a great atmosphere, where interesting and very smart personalities from various countries gather to address interesting research questions. I found this working atmosphere in our lab at EMBL and enjoyed spending lots of time with all of you. I especially enjoyed speaking different languages, though mostly our beloved English, having so many diverse cultural backgrounds around and I took pleasure from the fact that all of you are great characters. Therefore I want to thank all lab members for the very good time I had. This includes: Dr. Anne-Claude Gavin, Michaela Rode, Dr. Pedro Beltran, Ines Racké, Emma Dalton, Christian Matetzki, Jamie Trott, Jelena Gvozdenovic-Jeremic, Carmen Gurrieri Aguilar, Tomás Norambuena, Samuel Bader, Dr. Sebastian Charbonnier, Dr. Stefan Bonn, Dr. Oriol Gallego, Evelyn Sawa, Tatjana Schneidt, Dr. Emmanuel Poilpré, Dr. Kenji Maeda, Dr. Arun Kumar, Dr. Emmanuel Saliba, Dr. Jan Seebacher, Lisa Lirussi and Mattia Poletto.

Table S3: List of protein complexes. This table is a repository of all protein complexes that have been observed in this study. It is divided into i) a set of 116 heteromultimeric complexes and ii) a set of 62 homomultimeric complexes. In part i) the first column gives the assembly ID that specifies the higher order molecular assembly in which a heteromultimeric protein complex clusters. The second column specifies the unique complex ID for each protein complex. Columns 3 and 4 provide complex name and complex function, respectively. In columns 5-8 the systematic name, protein name, UniProt protein name and subunit type of each protein component of a complex are indicated. In part ii) the first column on the left shows the complex ID of the homomultimeric protein complexes. The second column indicates the complex name. Columns 3 and 4 give the annotated systematic and protein name of each homomultimer.
