CC   -!- FUNCTION: VirB proteins are suggested to act at the bacterial surface
CC       and there play an important role in directing T-DNA transfer to plant
CC       cells.
CC   -!- SUBUNIT: Interacts with host plant RTNLB1 protein. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cell outer membrane {ECO:0000305}; Multi-pass
CC       membrane protein {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the virB2 family. {ECO:0000305}.
