Web9.1 α-Chymotrypsin. α-Chymotrypsin (EC 3.4.21.1; chymotrypsinogen A) is a “hydrolytic enzyme” member of the super-family of serine proteases, enzymes that hydrolytically cleave peptide bonds utilizing a serine hydroxyl group as a nucleophile at the active site. The most extensively studied is bovine pancreatic chymotrypsin. WebActivation of chymotrypsinogen involves proteolytic cleavage at two sites along the chain and removal of two amino acids at each cleavage site. The resultant three chains are shown here (chain 1 = 1-13 in green; chain 2 = 16-146 in red; chain 3 = 149-24 in blue). Note, some amino acids at the temini of these chains are not shown in ths ...

WebCatalytic activity in trypsin proceeds by the utilization of an elegant arrangement of three-amino acid side chains that constitute the “catalytic triad” (Fig. 1).Using a numbering system based on chymotrypsinogen, this essential triumvirate consists of serine-195 (Ser 195), histidine-57 (His 57), and aspartate-102 (Asp 102).These three amino acids are strictly … Chymotrypsinogen is an inactive precursor (zymogen) of chymotrypsin, a digestive enzyme which breaks proteins down into smaller peptides.
