UniProtKB - Q0WRL9 (Q0WRL9_ARATH)
Protein
Methionine aminopeptidase 2
Gene
At2g44180
Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Functioni
Cotranslationally removes the N-terminal methionine from nascent proteins. The N-terminal methionine is often cleaved when the second residue in the primary sequence is small and uncharged (Met-Ala-, Cys, Gly, Pro, Ser, Thr, or Val).
UniRule annotationCatalytic activityi
- Release of N-terminal amino acids, preferentially methionine, from peptides and arylamides.UniRule annotationARBA annotation EC:3.4.11.18
Cofactori
Co2+UniRule annotation, Zn2+UniRule annotation, Mn2+UniRule annotation, Fe2+UniRule annotationNote: Binds 2 divalent metal cations per subunit. Has a high-affinity and a low affinity metal-binding site. The true nature of the physiological cofactor is under debate. The enzyme is active with cobalt, zinc, manganese or divalent iron ions. Most likely, methionine aminopeptidases function as mononuclear Fe2+-metalloproteases under physiological conditions, and the catalytically relevant metal-binding site has been assigned to the histidine-containing high-affinity site.UniRule annotation
