CC   -!- FUNCTION: Is essential for the biogenesis of the T-pilus, which is
CC       required for virulence and T-DNA transfer to plant cells. When is
CC       associated with virB9, might function as a nucleation center for
CC       recruitment of VirB proteins during assembly of the T-DNA transfer
CC       machine (By similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Homodimer and heterodimer of virB7 and virB9; disulfide-
CC       linked. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cell outer membrane; Lipid-anchor. Note=Also
CC       associated with the T-pilus when is a homodimer, possibly at the pilus
CC       base. {ECO:0000250}.
CC   -!- MISCELLANEOUS: Is protease-resistant. {ECO:0000250}.
CC   -!- MISCELLANEOUS: Both virB7 lipid modification and disulfide cross-
CC       linking are important for T-pilus assembly.
