CC -!- FUNCTION: Cotranslationally removes the N-terminal methionine from
CC nascent proteins. The N-terminal methionine is often cleaved when the
CC second residue in the primary sequence is small and uncharged (Met-
CC Ala-, Cys, Gly, Pro, Ser, Thr, or Val).
CC {ECO:0000256|RuleBase:RU003653}.
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:0000256|HAMAP-Rule:MF_03174,
CC ECO:0000256|RuleBase:RU003653};
CC -!- COFACTOR:
CC Name=Co(2+); Xref=ChEBI:CHEBI:48828;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_03174};
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_03174};
CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_03174};
CC Name=Fe(2+); Xref=ChEBI:CHEBI:29033;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_03174};
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:0000256|HAMAP-Rule:MF_03174};
CC -!- SIMILARITY: Belongs to the peptidase M24A family. Methionine
CC aminopeptidase type 1 subfamily. {ECO:0000256|HAMAP-Rule:MF_03174}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
