RC TISSUE=Leaf {ECO:0000313|RefSeq:XP_018474929.1}; RG RefSeq; RL Submitted (JUN-2020) to UniProtKB. 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 -!- 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 ECO:0000256|RuleBase:RU003653}; CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105; CC Evidence={ECO:0000256|HAMAP-Rule:MF_03175, CC ECO:0000256|RuleBase:RU003653}; CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035; CC Evidence={ECO:0000256|HAMAP-Rule:MF_03175, CC ECO:0000256|RuleBase:RU003653}; CC Name=Fe(2+); Xref=ChEBI:CHEBI:29033; CC Evidence={ECO:0000256|HAMAP-Rule:MF_03175, CC ECO:0000256|RuleBase:RU003653}; 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.
