In vivo, chymotrypsin is a proteolytic enzyme (serine protease) acting in the digestive systems of many organisms. It facilitates the cleavage of peptide bonds by a hydrolysis reaction, which despite being thermodynamically favorable, occurs extremely slowly in the absence of a catalyst. The main substrates of chymotrypsin are peptide bonds in which the amino acid N-termi… WebHere we show the mechanism of four enzymatic reactions: - PROTEASES is an enzyme that catalyzes the hydrolytic cleavage of peptide bonds.
