CC   -!- FUNCTION: Core component of the type II secretion system required for
CC       the energy-dependent secretion of extracellular factors such as
CC       proteases and toxins from the periplasm. Pseudopilin (pilin-like)
CC       protein that polymerizes to form the pseudopilus. Further
CC       polymerization triggers pseudopilus growth.
CC       {ECO:0000250|UniProtKB:Q00514}.
CC   -!- SUBUNIT: Type II secretion system is composed of four main components:
CC       the outer membrane complex, the inner membrane complex, the cytoplasmic
CC       secretion ATPase and the periplasm-spanning pseudopilus. Forms
CC       homomultimers. {ECO:0000250|UniProtKB:Q00514}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane
CC       {ECO:0000250|UniProtKB:Q00514}; Single-pass membrane protein
CC       {ECO:0000255}.
CC   -!- PTM: Cleaved by the prepilin peptidase. {ECO:0000250|UniProtKB:Q00514}.
CC   -!- PTM: Methylated by prepilin peptidase at the amino group of the N-
CC       terminal phenylalanine once the leader sequence is cleaved.
CC       {ECO:0000250|UniProtKB:Q00514}.
CC   -!- SIMILARITY: Belongs to the GSP G family. {ECO:0000305}.
