WebABSTRACT. To examine the enzyme kinetics of chymotrypsin during the catalysis of the synthetic substrate p-nitrophenyl acetate (NPA). Initially, observe the magnitude of the initial burst with regards to the enzyme concentration. Secondly, the analysis of the steady state deacylation rate with regards to the pH of the reaction mixture. WebStage 1: A polypeptide substrate moves into the active site of the enzyme. The shape, size, and amino acid sequence of chymotrypsin’s active site allow that part of the enzyme to bind a portion of a polypeptide that has nonpolar side chains, like those found in phenylalanine.

WebTwo new chromogenic substrates of chymotrypsin have been synthesized: N-succinyl-L-phenylalanine p-nitroanilide (SPNA) and N-glutaryl-L-phenylalanine p-nitroanilide (GPNA). … WebThe general mechanism for chymotrypsin is the classic serine protease mechanism. Hydrolytic proteolysis by alpha-chymotrypsin begins with initial nucleophilic attack on the peptide bond by Ser 195, activated by deprotonation by His 57. This leads to the formation of a tetrahedral intermediate, stabilised by the amide groups of Ser 195 and Gly 193. mandarin dream strain review
