Enzyme Information

3.4.11.18
Methionyl aminopeptidase.
based on mapping to UniProt P56218
Release of N-terminal amino acids, preferentially methionine, from peptides and arylamides.
-!- This membrane-bound enzyme, which is present in both prokaryotes and eukaryotes, releases the initiator methionine from nascent peptides. -!- The activity is dependent on the identity of the second, third and fourth amino acid residues of the target protein, but in general the enzyme acts only when the penultimate residue is small and uncharged (e.g. Gly, Ala, Cys, Ser, Thr, and Val). -!- Belongs to peptidase family M24A.
