Methionyl aminopeptidase
Class of enzymes
Methionyl aminopeptidase (EC 3.4.11.18, methionine aminopeptidase, peptidase M, L-methionine aminopeptidase, MAP) is an enzyme.[1][2][3][4][5] This enzyme catalyses the following chemical reaction
- Release of N-terminal amino acids, preferentially methionine, from peptides and arylamides
This membrane-bound enzymatic activity is present in both prokaryotes and eukaryotes. Human proteins possessing this activity include METAP1, METAP2, METAP1D (mitochondrial), and RNPEPL1.
