1 This residue, located at "canonical" position 255, where it is Ile in human pancreatic carboxypeptidases A1 (hCPA1) and A2 (hCPA2) and Asp in B (hCPB), plays a dominant role in determining the preference of hCPO for acidic C-t residues. Aspartic Acid carboxypeptidase O Homo sapiens
2 hCPO also shows a preference for Glu over Asp, probably as a consequence of a tighter fitting of the Glu side chain in its S1" substrate-binding pocket. Aspartic Acid carboxypeptidase O Homo sapiens
