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   -!- SIMILARITY: Belongs to the virb1 family. {ECO:0000305}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=CAA37354.1; Type=Erroneous initiation; Evidence={ECO:0000305};
