[Kinetics of low molecular weight substrate hydrolysis by immobilized trypsin].
The catalytic properties of trypsin immoblized on silochrome were studied in a flow reactor with replacement. The hydrolysis of methyl ester N-n-tosyl-L-arginine obeys the Michaelis--Menten kinetics. The apparent K'm value for the system with immobilized trypsin is considerably lower than for native trypsin. The K'm value was decreased with an increase in the rate of the substrate flow through the reactor or when smaller-sized silochrome granules were used. It is assumed that the apparent K'm value for the immobilized system is due to diffusion. The effects of diffusion on the catalytic properties of the immobilized enzyme were estimated.
