[Dynamic theory of enzymatic catalysis]

Formal kinetics of an enzymatic reaction is considered in terms of a dynamic scheme of catalysis. Conformation reconstructions of a liberated enzyme and e-s-complex are analysed upon the phase plane. An expression for the enzyme stationary activity depending on the rate of conformation reconstructions is obtained. The case of purely dynamic catalysis is analysed and possible initiation of enzymatic activity variation in time connected with initial synchronization of molecules is shown. This phenomenon is considered as a possible criterion of the dynamic character of enzymatic catalysis.
