Activity
Type I, <0.1 units/mg protein; Type II, 100,000-250,000 units/g solid (without added oxygen); Type III, 2,000-10,000 units/g solid (without added oxygen); Type IV, 15,000-50,000 units/g solid (without added oxygen); Type V, > 100,000 units/g solid (without added oxygen); Type VI, ~200 units/mg; Type VII, > 15,000 units/g solid (without added oxygen).
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%.
Reaction
β-D-glucose + O2 = D-glucono-1,5-lactone + H2O2
