Description
ProductName Native Cucurbita sp. L-ascorbate oxidase Cat No DIA-124 Description 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. Abbr L-ascorbate oxidase (Cucurbita sp.) Source Cucurbita sp. Applications This enzyme is useful for enzymatic determination of ascorbic acid and for eliminating the interference of ascorbic acid in clinical analysis. Appearance Light blue amorphous powder, lyophilized Product Overview Native L-ascorbate oxidase (EC 1.10.3.3) was purified from Acremonium sp.. Form Light blue lyophilized powder. Enzyme Commission Number EC 1.10.3.3 Activity 40U/mg CAS No 9029-44-1 Contaminants Catalase < 1.0×10⁻¹ % Phosphatase < 2.0×10⁻² % pH Stability pH 6.0-10.0 (25°C, 20hr) Michaelis Constant 3.0×10-4M(Ascorbate) Specificity The enzyme oxidizes ascorbic acid and several ascorbic acid derivatives. Unit Definition One unit causes the decrease of one micromole of ascorbic acid per minute under the conditions described below. Optimum pH 6 Thermal stability below 45°C (pH 7.0, 30min) Stability Stable at-20°C for at least one year Storage Store in tightly closed containers, desiccated, protected from light, at-20°C.
