Is host lipidation of pathogen effector proteins a general virulence
... (Price et al., 2010b) several Legionella strains encode a number of CAAX motifcontaining proteins and most of them are effectors. Thus, an important question raised is whether the exploitation of host lipidation machinery is a widely used virulence strategy. Price et al. (2010a) searched for CAAX ...

Type three secretion system
Type three secretion system (often written Type III secretion system and abbreviated TTSS or T3SS, also called Injectisome or Injectosome) is a protein appendage found in several Gram-negative bacteria.In pathogenic bacteria, the needle-like structure is used as a sensory probe to detect the presence of eukaryotic organisms and secrete proteins that help the bacteria infect them. The secreted effector proteins are secreted directly from the bacterial cell into the eukaryotic (host) cell, where they exert a number of effects that help the pathogen to survive and to escape an immune response.
