CC -!- FUNCTION: Plays an essential role in type IV pili and type II
CC pseudopili formation by proteolytically removing the leader sequence
CC from substrate proteins and subsequently monomethylating the alpha-
CC amino group of the newly exposed N-terminal phenylalanine.
CC {ECO:0000256|RuleBase:RU003794}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Typically cleaves a -Gly-|-Phe- bond to release an N-terminal,
CC basic peptide of 5-8 residues from type IV prepilin, and then N-
CC methylates the new N-terminal amino group, the methyl donor being S-
CC adenosyl-L-methionine.; EC=3.4.23.43;
CC Evidence={ECO:0000256|RuleBase:RU003794};
CC -!- SUBCELLULAR LOCATION: Cell inner membrane
CC {ECO:0000256|ARBA:ARBA00004429}; Multi-pass membrane protein
CC {ECO:0000256|ARBA:ARBA00004429}. Cell membrane
CC {ECO:0000256|RuleBase:RU003794}; Multi-pass membrane protein
CC {ECO:0000256|RuleBase:RU003794}. Membrane
CC {ECO:0000256|ARBA:ARBA00004141}; Multi-pass membrane protein
CC {ECO:0000256|ARBA:ARBA00004141}.
CC -!- SIMILARITY: Belongs to the peptidase A24 family.
CC {ECO:0000256|ARBA:ARBA00005801, ECO:0000256|RuleBase:RU003793}.
