Family: VirJ

Block: X

Parent Family: No family


Bacterial virulence protein (VirJ). This family contains several bacterial VirJ virulence proteins. VirJ is in the vir region of an octopine-type Ti plasmid. VirJ is similar to of a chromosomal gene acvB, which is required for tumorigenesis. Any one of these genes are required for T-DNA transfer into plants. VirJ is thought to be involved in the type IV secretion system. It is thought that the substrate proteins localised to the periplasm may associate with the pilus in a manner that is mediated by VirJ, and suggest a two-step process for type IV secretion in Agrobacterium. Also contains a periplasmic Aminoacyl-phosphatidylglycerol Hydrolase Responsible for Pseudomonas aeruginosa Lipid Homeostasis
