CC   -!- FUNCTION: Component of the type II secretion system required for the
CC       energy-dependent secretion of extracellular factors such as proteases
CC       and toxins from the periplasm. Part of the pseudopilus tip complex that
CC       is critical for the recognition and binding of secretion substrates.
CC       {ECO:0000250|UniProtKB:Q00516}.
CC   -!- SUBUNIT: Type II secretion is composed of four main components: the
CC       outer membrane complex, the inner membrane complex, the cytoplasmic
CC       secretion ATPase and the periplasm-spanning pseudopilus. Interacts with
CC       core component OutG. {ECO:0000250|UniProtKB:Q00516}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane
CC       {ECO:0000250|UniProtKB:Q00516}; Single-pass membrane protein
CC       {ECO:0000255}.
CC   -!- PTM: Cleaved by prepilin peptidase. {ECO:0000250|UniProtKB:Q00516}.
CC   -!- PTM: Methylated by prepilin peptidase at the amino group of the N-
CC       terminal methionine once the leader sequence is cleaved by prepilin
CC       peptidase. {ECO:0000250|UniProtKB:Q00516}.
CC   -!- SIMILARITY: Belongs to the GSP I family. {ECO:0000305}.
