Enzyme Information
| 7.2.1.3 |
Ascorbate ferrireductase (transmembrane).
based on mapping to UniProt Q9SWS1
Ascorbate(Side 1) + Fe(III)(Side 2) = monodehydroascorbate(Side 1) + Fe(II)(Side 2).
-!- A diheme cytochrome that transfers electrons across a single membrane, such as the outer membrane of the enterocyte, or the tonoplast membrane of the plant cell vacuole. -!- Acts on hexacyanoferrate(III) and other ferric chelates. -!- Formerly EC 1.16.5.1.
