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 (PubMed:9282737). Part of the pseudopilus
CC tip complex that is critical for the recognition and binding of
CC secretion substrates (PubMed:19828448). Type II pseudopilus confers
CC increased bacterial adhesive capabilities (PubMed:12700254).
CC {ECO:0000269|PubMed:12700254, ECO:0000269|PubMed:19828448,
CC ECO:0000269|PubMed:9282737}.
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. Forms the tip
CC of the type II pseudopilus by interacting with XcpU, XcpW and XcpX
CC (PubMed:19828448, PubMed:30346996). Interacts with core component XcpT
CC (PubMed:9282737). {ECO:0000269|PubMed:19828448,
CC ECO:0000269|PubMed:30346996, ECO:0000269|PubMed:9282737}.
CC -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000269|PubMed:8331069};
CC Single-pass membrane protein {ECO:0000255}.
CC -!- PTM: Cleaved by prepilin peptidase. {ECO:0000269|PubMed:8331069}.
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:0000269|PubMed:8331069}.
CC -!- DISRUPTION PHENOTYPE: Deletion mutant results in a non-functional T2SS
CC system. {ECO:0000269|PubMed:30346996}.
CC -!- SIMILARITY: Belongs to the GSP I family. {ECO:0000305}.
