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). {ECO:0000256|HAMAP-
CC Rule:MF_03175, ECO:0000256|RuleBase:RU003653}.
CC -!- FUNCTION: Protects eukaryotic initiation factor EIF2S1 from
CC translation-inhibiting phosphorylation by inhibitory kinases such as
CC EIF2AK2/PKR and EIF2AK1/HCR. Plays a critical role in the regulation of
CC protein synthesis. {ECO:0000256|HAMAP-Rule:MF_03175}.
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|ARBA:ARBA00000294, ECO:0000256|HAMAP-
CC Rule:MF_03175, ECO:0000256|RuleBase:RU003653};
CC -!- COFACTOR:
CC Name=Co(2+); Xref=ChEBI:CHEBI:48828;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_03175};
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_03175};
CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_03175};
CC Name=Fe(2+); Xref=ChEBI:CHEBI:29033;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_03175};
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_03175};

CC Name=Fe(2+); Xref=ChEBI:CHEBI:29033;
CC Evidence={ECO:0000256|ARBA:ARBA00001954};
CC -!- COFACTOR:
CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035;
CC Evidence={ECO:0000256|ARBA:ARBA00001936};
CC -!- SUBUNIT: Binds EIF2S1 at low magnesium concentrations. Interacts
CC strongly with the eIF-2 gamma-subunit EIF2S3. {ECO:0000256|HAMAP-
CC Rule:MF_03175}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_03175}.
CC Note=About 30% of expressed METAP2 associates with polysomes.
CC {ECO:0000256|HAMAP-Rule:MF_03175}.
CC -!- PTM: Contains approximately 12 O-linked N-acetylglucosamine (GlcNAc)
CC residues. O-glycosylation is required for EIF2S1 binding.
CC {ECO:0000256|HAMAP-Rule:MF_03175}.
CC -!- SIMILARITY: Belongs to the peptidase M24A family. Methionine
CC aminopeptidase eukaryotic type 2 subfamily. {ECO:0000256|HAMAP-
CC Rule:MF_03175}.
