Usage

Description

Ascorbate oxidase (AO) is a cell wall-localized enzyme that uses oxygen to catalyze the oxidation of ascorbate (AA) to the unstable radical monodehydroascorbate (MDHA), which rapidly disproportionates to yield dehydroascorbate (DHA) and AA, thus contributing to the regulation of the AA redox state.

Uses

Used in Enzymatic Determination of Ascorbic Acid:
Ascorbate oxidase is used as an enzymatic tool for the determination of ascorbic acid levels, providing a reliable method for measuring this essential nutrient.
Used in Eliminating Interference of Ascorbic Acid in Clinical Analysis:
Ascorbate oxidase is employed to eliminate the interference of ascorbic acid in clinical analysis, ensuring accurate and precise results in various diagnostic tests.
Used in Studying Oxidative Stress and Heat Stress Response and Tolerance:
Ascorbate oxidase, from Cucurbita sp., is used as a research tool to study oxidative stress and heat stress response and tolerance, providing insights into the mechanisms of these stressors in biological systems.
Used in Ascorbic Acid Assays for Studying Heat Stress Response of Arabidopsis:
Ascorbate oxidase is utilized in ascorbic acid assays to study the heat stress response of Arabidopsis, a model plant species, helping researchers understand the plant's response to environmental stressors.

Biochem/physiol Actions

Ascorbate oxidase (AO) participates in cell growth by regulating reduction/oxidation (redox) of the apoplast. This enzyme can synthesize the oxidative molecule dehydroascorbate acid (DHA) in the apoplast. It is also involved in cell elongation and enlargement development.
