The Ti Plasmid‐Encoded VirJ Functions as a Lysyl‐Phosphatidylglycerol Hydrolase in Agrobacterium tumefaciens

open access: yesMolecular Microbiology, Volume 125, Issue 5, Page 426-441, May 2026.
We identify the long‐known virulence factor VirJ as a lysyl‐phosphatidylglycerol (L‐PG) hydrolase. Like the chromosomally encoded virulence factor AcvB, it prevents excessive accumulation of L‐PG in the membrane, thereby maintaining efficient T‐DNA transfer via the Type IV secretion system (T4SS) in Agrobacterium tumefaciens.
