The effect of bound to dialdehudecellulose protein concentration on the activity of immobilized trypsin after γ-irradiation and in process of storage

It is found the complex effect of the bound enzyme concentration on the proteolytic activity of trypsin immobilized to dialdehydecellulose (preriodate oxidation) after γ-irradiation and in process of storage. It is shown the occurance of three stages of immobilized enzyme inactivation in process of immobilization and storage. The velocity of inactivation did not depend on bound trypsin concentration. The ratio of proteolytic activity of samples before and after γ-irradiation was increased with the increase of immobilized to carrier enzyme concentration and was not change (in range of experiment error) in process of storage. The results were compared with that of cryctlline trypsin
