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   -!- SUBCELLULAR LOCATION: Membrane {ECO:0000305}; Multi-pass membrane
CC       protein {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the TrbL/VirB6 family. {ECO:0000305}.
