is chymotrypsin a catalyst
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 include tryptophan, tyrosine, phenylalanine, and leucine, which are cleaved at the carboxyl terminal.t was found that the reaction of chymotrypsin with its substrate takes place in two stages, an initial âburstâ phase at the beginning of the reaction and a steady-state phase following Michaelis-Menten kinetics.
