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.
A model peptide of 12 amino acids (gly193-asn204) that spans the gamma chymotrypsin protein (at left) is used to illustrate example bonds in a known structure. The gamma chymotrypsin protein consists of four peptide chains (A, B, C, D), generated by cleavage of a precursor polypeptide.
