oxidation affects the functional properties of the two inhibitors differently : the antiproteolytic activity of bpti towards bovine trypsin and chymotrypsin , porcine kallikrein and human leukocyte elastase is not changed upon oxidation , while in the oxidized si ii , the affinity for both chymotrypsin and elastase decreases , with respect to the native protein .
