Methionyl aminopeptidase

Methionyl aminopeptidase (, methionine aminopeptidase, peptidase M, L-methionine aminopeptidase, MAP) is an enzyme. 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.
