[Kinetic regularities of S2'-stimulation of alpha-chymotrypsin].

Data on the kinetics of S2'-stimulated alpha-chymotrypsin action have been presented. It is supposed that the increase of the catalytic action of S2'-stimulated chymotrypsin occurs at all three stages of the hydrolytic process-at the enzyme-substrate complex formation, its transformation to covalent acyl-enzyme and at the hydrolysis of the latter.
