Chymotrypsin inhibitor mechanism
WebAutolysis of chymotrypsin and its possible degradation by other proteases represents one of the physiologic mechanisms for the inactivation of chymotrypsin in the small intestine. The other mechanism to regulate the activity of serine proteases is their inhibition by pancreatic protease inhibitors and serpins. WebThe chymotrypsin inhibitor activity is defined as the number of chymotrypsin units inhibited (CUI), and the results can be expressed as CUI per milligram of protein or per …
