Protein

Methionine aminopeptidase 1

Gene

MAP1

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

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). Plays the major role in N-terminal methionine removal. Less efficient when the second residue is Val.UniRule annotation4 Publications

Catalytic activityi

Release of N-terminal amino acids, preferentially methionine, from peptides and arylamides.UniRule annotation

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

Enzyme regulationi

In contract to the MetAP 2 isoform, is not inhibited by the fungal metabolite fumagillin, an antiangiogenic drug.1 Publication

Kineticsi

Kcat is 1173, 1416 and 507 (Min-1) with a Met-Ala-Ser, a Met-Gly-Met-Met and a Met-Ala-Ser-Trp peptide substrate, respectively.
