WebChymotrypsinogen A may be activated by trypsin and chymotrypsin (autolytic activation) to form m α, β, γ, δ and π chymotrypsin (depending upon the conditions of activation). Chymotrypsin is a protease that will preferentially cleave peptides on the carboxyl side of aromatic amino acids including tryptophan, tyrosine, and phenylalanine. WebHowever, due to the presence of gastric juice, chymotrypsin often functions in an environment of pH 5.5-7.0. The imidazole group of free histidine has a pKof 6.0.
