ENZYME entry: EC 1.11.1.11
Accepted Name |
L-ascorbate peroxidase.
|
Alternative Name(s) |
Ascorbic acid peroxidase. |
Reaction catalysed |
2 L-ascorbate + H(2)O(2) + 2 H(+) <=> L-ascorbate + L-dehydroascorbate + 2 H(2)O |
Cofactor(s) |
Heme.
|
Comment(s) |
- 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.
