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.
