| Comments | Chymotrypsin A is formed from cattle and pig chymotrypsinogen A, several iso-forms being produced according to the number of bonds hydrolysed in the precursor. Formerly EC?3.4.4.5. Chymotrypsin B, formerly EC?3.4.4.6, formed from chymotrypsinogen B, is homologous with chymotrypsin A. Enzymes with specificity similar to that of chymotrypsins A and B have been isolated from many species. In peptidase family?S1?(trypsin family). |
