ID A0A125S6H1_9FUNG Unreviewed; 352 AA. AC A0A125S6H1; DT 13-APR-2016, integrated into UniProtKB/TrEMBL. DT 13-APR-2016, sequence version 1. DT 25-OCT-2017, entry version 12. DE RecName: Full=Methionine aminopeptidase {ECO:0000256|RuleBase:RU003653}; DE EC=3.4.11.18 {ECO:0000256|RuleBase:RU003653}; OS Actinomucor elegans. OC Eukaryota; Fungi; Mucoromycota; Mucoromycotina; Mucorales; Mucorineae; OC Mucoraceae; Actinomucor. OX NCBI_TaxID=64647 {ECO:0000313|EMBL:AME15507.1}; RN [1] {ECO:0000313|EMBL:AME15507.1} RP NUCLEOTIDE SEQUENCE. RA Murphy D.; RL Submitted (MAR-2015) to the EMBL/GenBank/DDBJ databases. 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). {ECO:0000256|RuleBase:RU003653}. CC -!- CATALYTIC ACTIVITY: Release of N-terminal amino acids, CC preferentially methionine, from peptides and arylamides. CC {ECO:0000256|HAMAP-Rule:MF_03174, ECO:0000256|RuleBase:RU003653}. CC -!- COFACTOR: CC Name=Co(2+); Xref=ChEBI:CHEBI:48828; Evidence={ECO:0000256|HAMAP- CC Rule:MF_03174, ECO:0000256|RuleBase:RU003653}; CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105; Evidence={ECO:0000256|HAMAP- CC Rule:MF_03174, ECO:0000256|RuleBase:RU003653}; CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035; Evidence={ECO:0000256|HAMAP- CC Rule:MF_03174, ECO:0000256|RuleBase:RU003653}; CC Name=Fe(2+); Xref=ChEBI:CHEBI:29033; Evidence={ECO:0000256|HAMAP- CC Rule:MF_03174, 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_03174, ECO:0000256|RuleBase:RU003653}; CC -!- SIMILARITY: Belongs to the peptidase M24A family. Methionine CC aminopeptidase type 1 subfamily. {ECO:0000256|HAMAP- CC Rule:MF_03174}.
