Crystal structure of porcine aminopeptidase N ectodomain in functional form

Released:

Function and Biology Details

Reaction catalysed:
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.
