Protein

Methionine aminopeptidase

Gene

map

Organism
Treponema pallidum (strain Nichols)
Status
Reviewed - Annotation score: 3 out of 5- Protein inferred from homologyi

Functioni

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). Requires deformylation of the N(alpha)-formylated initiator methionine before it can be hydrolyzed.UniRule annotation

Catalytic activityi

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

Cofactori

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
