Unit Definition
One unit will oxidize 1.0 μmole of β-D-glucose to D-gluconolactone and H2O2 per min at pH 5.1 at 35 °C, equivalent to an O2 uptake of 22.4 μl per min. If the reaction mixture is saturated with oxygen, the activity may increase by up to 100%.

Description
Glucose oxidase is a well-characterised flavoprotein that catalyses oxidation of β-D-Glucose at its first hydroxyl group, utilizing molecular oxygen as the electron acceptor, to produce D-glucono-delta-lactone and hydrogen peroxide. Glucose oxidase is a homodimeric enzyme, with an FAD molecule moncovalently but tightly bound at the active site of each 80 KDa subunit. The enzyme consists of two identical polypeptide chain subunits (80,000 Daltons) covalently linked by disulfide bonds. Each subunit contains one mole of Fe and one mole of FAD (flavin-adenine dinucleotide). The molecule consists of approximately 74% protein, 16% neutral sugar and 2% amino sugars. The FAD is replaceable with FHD (flavin-hypoxanthine dinucleotide) without loss of activity.
