Its precursor is chymotrypsinogen. Trypsin activates chymotrypsinogen by cleaving peptidic bonds in positions Arg15 – Ile16 and produces π-chymotrypsin. In turn, aminic group (-NH3 ) of the Ile16 residue interacts with the side chain of Asp194, producing the "oxyanion hole" and the hydrophobic "S1 pocket". Moreover, chymotrypsin induces its own activation by cleaving in positions 14–15, 146–147, and 148–149, producing α-c… the principal varieties of mankindWebJan 1, 1974 · The pH optimum for the hydrolysis of casein by chymotrypsin is pH 8.01.
