Functional Family Putative aminopeptidase N

Enzyme Information

3.4.11.2
Membrane alanyl aminopeptidase.
based on mapping to UniProt P04825
Release of an N-terminal amino acid, Xaa-|-Yaa- from a peptide, amide or arylamide. Xaa is preferably Ala, but may be most amino acids including Pro (slow action). When a terminal hydrophobic residue is followed by a prolyl residue, the two may be released as an intact Xaa-Pro dipeptide.
-!- Is not activated by heavy metal ions. -!- Belongs to peptidase family M1. -!- Formerly EC 3.4.1.2, EC 3.4.3.5 and EC 3.4.13.6.
