CC -!- FUNCTION: Removes the N-terminal methionine from nascent proteins. The
CC N-terminal methionine is often cleaved when the second residue in the
CC primary sequence is small and uncharged (Met-Ala-, Cys, Gly, Pro, Ser,
CC Thr, or Val). Requires deformylation of the N(alpha)-formylated
CC initiator methionine before it can be hydrolyzed. {ECO:0000255|HAMAP-
CC Rule:MF_01974}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Release of N-terminal amino acids, preferentially methionine,
CC from peptides and arylamides.; EC=3.4.11.18;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01974};
CC -!- COFACTOR:
CC Name=Co(2+); Xref=ChEBI:CHEBI:48828;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01974};
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01974};
CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01974};
CC Name=Fe(2+); Xref=ChEBI:CHEBI:29033;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01974};
CC Note=Binds 2 divalent metal cations per subunit. Has a high-affinity
CC and a low affinity metal-binding site. The true nature of the
CC physiological cofactor is under debate. The enzyme is active with
CC cobalt, zinc, manganese or divalent iron ions. Most likely, methionine
CC aminopeptidases function as mononuclear Fe(2+)-metalloproteases under
CC physiological conditions, and the catalytically relevant metal-binding
CC site has been assigned to the histidine-containing high-affinity site.
CC {ECO:0000255|HAMAP-Rule:MF_01974};
CC -!- SUBUNIT: Monomer. {ECO:0000255|HAMAP-Rule:MF_01974}.
CC -!- SIMILARITY: Belongs to the peptidase M24A family. Methionine
CC aminopeptidase type 1 subfamily. {ECO:0000255|HAMAP-Rule:MF_01974}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AAF38634.1; Type=Erroneous initiation; Evidence={ECO:0000305};
CC Sequence=AAP98976.1; Type=Erroneous initiation; Evidence={ECO:0000305};
