Biochem/physiol Actions

Broad-spectrum inhibitor of carboxypeptidases of animal digestive-tract origin, but little or no activity against plant and microbial carboxypeptidases. However, recent results suggest it may play a part in resistance to microbial pathogens by preventing digestion of protein.
