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:Q00517}.
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 GspG. {ECO:0000250|UniProtKB:Q00517}.
CC -!- SUBCELLULAR LOCATION: Cell inner membrane
CC {ECO:0000250|UniProtKB:Q00517}; Single-pass membrane protein
CC {ECO:0000255}.
CC -!- INDUCTION: Silenced by the DNA-binding protein H-NS under standard
CC growth conditions. {ECO:0000269|PubMed:11118204}.
CC -!- PTM: Cleaved by prepilin peptidase. {ECO:0000250|UniProtKB:Q00517}.
CC -!- PTM: Methylated by prepilin peptidase at the amino group of the N-
CC terminal phenylalanine once the leader sequence is cleaved by prepilin
CC peptidase. {ECO:0000250|UniProtKB:Q00517}.
CC -!- MISCELLANEOUS: Part of a cryptic operon that encodes proteins involved
CC in type II secretion machinery in other organisms, but is not expressed
CC in strain K12.
CC -!- SIMILARITY: Belongs to the GSP J family. {ECO:0000305}.
