... for the feedback loop, and the model of the core oscillator as a single negative feedback loop (Crosthwaite et al. 1997). Later work established that FRQ actually binds to and inhibits the activity of its own transcription activators, the WCC (Cheng et al. 2001a; Denault et al. 2001; Froehlich et a ...

Most of the PTMs are catalyzed by specialized enzymes. Practically all proteinogenic amino acids can be modified, thus PTMs co ...

Puffs and PCR: the in vivo dynamics of early gene

... to establish profiles of early gene transcripts in a number of tissues. We confirm the precision of the biological system as shown by the studies of Karim and Thummel (1991, 1992) and reveal unsuspected detail in both the temporal and spatial response. We show that EcR transcript levels in the saliv ...

Receptor tyrosine kinases such as cMet can be activated by altering the catalytic domain conformation through an autophosphorylation reaction. cMet is a key regulator in a subset of cancers, in part, through activating oncogenic mutations which affect downstream signal transduction. cMet and eight c ...

The total number of amino acid residues varies among different PDK isomers, for example PDK1 has 436 residues, PDK2 and PDK4 have 407 residues and PDK3 has 406 residues [35]. The G ...

... catalyses the HCO3 − - and MgATP-dependent carboxylation of pyruvate to form oxaloacetate. This is a very important anaplerotic reaction, replenishing oxaloacetate withdrawn from the tricarboxylic acid cycle for various pivotal biochemical pathways. PC is therefore considered as an enzyme that is cr ...

... LysRS, ProRS, PheRS, and ThrRS are less accurate and have the ability to misactivate non-cognate amino acids (reaction 1). Misactivation occurs because there is a limited scope for structural variation among related amino acids. Pauling first recognized this problem in 1957, well before the mechanis ...
