Kinetics and Stability of Immobilized Glucose Oxidase and Catalase

Glucose oxidase (GOD) has been immobilized for both technical and analytical purposes. Since it is deactivated by its reaction product H202 (1), its activity may be stabilized by immobilized catalase (2). The catalase decomposes H202, but it is itself also deactivated by H202 (3). It therefore becomes necessary to analyze the production and decomposition rates of H202 and the deactivation rates for both enzymes in the presence of this compound.
