The pH dependence of the rate of glucose oxidase-catalyzed reactions in the presence of oxygen and artificial electron acceptors was studied. In contrast to the reaction involving oxygen, in which the maxima of the pH activity profile were observed at pH 5.6, glucose oxidase reveals maximal pH activity profile at pH 7.5 -- 7.6 in the presence of phenasine methosulfate, basic dark-blue 2K, viologens and ion-radical salt of N,N,N',N'-tetramethyl-rho-phenylene diamine. It was assumed that there exist two forms of the reduced enzyme differing in their rates of oxidation by oxygen and in ability to reduce artificial electron acceptors via one-electron transfer.
