CC   -!- FUNCTION: Removes the N-terminal methionine from nascent proteins.
CC       The N-terminal methionine is often cleaved when the second residue
CC       in the primary sequence is small and uncharged (Met-Ala-, Cys,
CC       Gly, Pro, Ser, Thr, or Val). Requires deformylation of the
CC       N(alpha)-formylated initiator methionine before it can be
CC       hydrolyzed. {ECO:0000256|HAMAP-Rule:MF_01974}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=Release of N-terminal amino acids, preferentially
CC         methionine, from peptides and arylamides.; EC=3.4.11.18;
CC         Evidence={ECO:0000256|HAMAP-Rule:MF_01974,
CC         ECO:0000256|RuleBase:RU003653};
CC   -!- COFACTOR:
CC       Name=Co(2+); Xref=ChEBI:CHEBI:48828; Evidence={ECO:0000256|HAMAP-
CC         Rule:MF_01974, ECO:0000256|RuleBase:RU003653};
CC       Name=Zn(2+); Xref=ChEBI:CHEBI:29105; Evidence={ECO:0000256|HAMAP-
CC         Rule:MF_01974, ECO:0000256|RuleBase:RU003653};
CC       Name=Mn(2+); Xref=ChEBI:CHEBI:29035; Evidence={ECO:0000256|HAMAP-
CC         Rule:MF_01974, ECO:0000256|RuleBase:RU003653};
CC       Name=Fe(2+); Xref=ChEBI:CHEBI:29033; Evidence={ECO:0000256|HAMAP-
CC         Rule:MF_01974, ECO:0000256|RuleBase:RU003653};
CC       Note=Binds 2 divalent metal cations per subunit. Has a high-
CC       affinity and a low affinity metal-binding site. The true nature of
CC       the physiological cofactor is under debate. The enzyme is active
CC       with cobalt, zinc, manganese or divalent iron ions. Most likely,
CC       methionine aminopeptidases function as mononuclear Fe(2+)-
CC       metalloproteases under physiological conditions, and the
CC       catalytically relevant metal-binding site has been assigned to the
CC       histidine-containing high-affinity site. {ECO:0000256|HAMAP-
CC       Rule:MF_01974, ECO:0000256|RuleBase:RU003653};
CC   -!- SUBUNIT: Monomer. {ECO:0000256|HAMAP-Rule:MF_01974}.
CC   -!- SIMILARITY: Belongs to the peptidase M24A family. Methionine
CC       aminopeptidase type 1 subfamily. {ECO:0000256|HAMAP-
CC       Rule:MF_01974}.
