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 … WebFeb 27, 1975 · Chymotrypsinogen A, the major chymotryptic component (90% of the total potential N-acetyl-L-tyrosine ethylester activity) is stable in acidic medium. By its molecular weight (approx. 24 000), specific activity (530) and amino acid composition, human chymotrypsinogen A resembles chymotrypsinogens A and B form bovine and porcine …

Webchymotrypsin: [noun] a protease that hydrolyzes peptide bonds and is formed in the intestine from chymotrypsinogen. 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 ... rbks construction
