Stoichiometry of the reaction catalyzed by skin sulfhydryl oxidase.
The stoichiometry of the reaction catalyzed by skin sulfhydryl oxidase was investigated. Dithiothreitol (DTT) was used as the substrate for skin sulfhydryl oxidase. The consumption of DTT, consumption of oxygen, and production of hydrogen peroxide were measured during the enzyme reaction. The molar ratio of DTT:O2:H2O2 in the enzyme reaction was 1:1.02:0.89. Correspondingly, the stoichiometry of the enzyme reaction was calculated to be [formula: see text]
