Functional Family Cytosolic ascorbate peroxidase

Enzyme Information

1.11.1.11
L-ascorbate peroxidase.
based on mapping to UniProt P48534
2 L-ascorbate + H(2)O(2) + 2 H(+) = L-ascorbate + L-dehydroascorbate + 2 H(2)O.
-!- Oxidizes ascorbate and low molecular weight aromatic substrates. -!- The monodehydroascorbate radical produced is either directly reduced back to ascorbate by EC 1.6.5.4 or undergoes non-enzymatic disproportionation to ascorbate and dehydroascorbate.
