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:0000250|UniProtKB:P22610}.
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:0000250|UniProtKB:P22610};
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000250|UniProtKB:P22610};
CC Note=Zinc is required for the N-terminal methylation of the mature
CC pilin, but not for signal peptide cleavage.
CC {ECO:0000250|UniProtKB:P22610};
CC -!- SUBCELLULAR LOCATION: Cell inner membrane
CC {ECO:0000250|UniProtKB:P22610}; Multi-pass membrane protein
CC {ECO:0000250|UniProtKB:P22610}.
CC -!- SIMILARITY: Belongs to the peptidase A24 family. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AAD05189.1; Type=Erroneous initiation; Note=Truncated N-terminus.; Evidence={ECO:0000305};
