La chymotrypsine est produite par le pancréas sous une forme inactive appelée le chymotrypsinogène. L'activation est provoquée par la trypsine qui coupe cette molécule en deux chaînes, puis par la chymotrypsine elle-même lors d'une trans-protéolyse, donnant à la fin une structure globulaire compacte de trois chaînes reliées par deux ponts disulfures et repliées en 2 domaines de 120 acides aminés.
