DIA-124 L-ascorbate oxidase (Cucurbita sp.)AAOCucurbita sp.In enzymology, a L-ascorbate oxidase (EC 1.10.3.3) is an enzyme that catalyzes the chemical reaction2 L-ascorbate + O2 ↔ 2 dehydroascorbate + 2 H2O. Thus, the two substrates of this enzyme are L-ascorbate and O2, whereas its two products are dehydroascorbate and H2O.This enzyme is useful for enzymatic determination of ascorbic acid and for eliminating the interference of ascorbic acid in clinical analysis.Light blue amorphous powder, lyophilizedNative L-ascorbate oxidase (EC 1.10.3.3) was purified from Acremonium sp..Light blue lyophilized powder.EC 1.10.3.3200U/mg9029-44-1Catalase < 1.0×10⁻¹ % Phosphatase < 2.0×10⁻² %pH 6.0-10.0 (25°C, 20hr)3.0×10-4M(Ascorbate)The enzyme oxidizes ascorbic acid and several ascorbic acid derivatives.One unit causes the decrease of one micromole of ascorbic acid per minute under the conditions described below.6below 45°C (pH 7.0, 30min)Stable at-20°C for at least one yearStore in tightly closed containers, desiccated, protected from light, at-20°C.cyanide, Na₂S, diethyldithiocarbamate (Na)ascorbase; ascorbic acid oxidase; ascorbate oxidase; ascorbic oxidase; ascorbate dehydrogenase; L-ascorbic acid oxidase; AAO; L-ascorbate: O2 oxidoreductase; AA oxidase; EC 1.10.3.3; 9029-44-1; L-ascorbate oxidase Download Datasheet:
