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.
CC       {ECO:0000269|PubMed:15494553}.
CC   -!- INTERACTION:
CC       P09776; P0A3W0: virB4; NbExp=2; IntAct=EBI-6509119, EBI-6509107;
CC   -!- SUBCELLULAR LOCATION: Cell outer membrane {ECO:0000305}; Multi-pass
CC       membrane protein {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the virB2 family. {ECO:0000305}.
