The X-ray crystalstructure of the complex of carboxypeptidase A (CPA) and Gly-Tyr, has been documented. The crystalstructure reveals that both the amide carbonyl oxygen and the terminal amino nitrogen of Gly-Tyr coordinate to the active site zinc ion of CPA in a bidentate fashion, whereby the zinc-bound water molecule is displaced by the amino group. As to the catalytic mechanism of CPA, it is generally
