Function
Ascorbate peroxidase (APX) catalyzes the conversion of ascorbate and hydrogen peroxide to dehydroascorbate and water thus detoxifying hydrogen peroxide. APX is involved in the glutathione-ascorbate cycle. APX is accumulated in plants in response to heat and drought stress. APX contains a heme group.
