Enzyme Information
| 1.11.1.5 |
Cytochrome-c peroxidase.
based on mapping to UniProt P00431
2 ferrocytochrome c + H(2)O(2) = 2 ferricytochrome c + 2 H(2)O.
|
| 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.
