Enzyme Information
| 1.8.7.2 |
Ferredoxin:thioredoxin reductase.
based on mapping to UniProt Q55389
2 reduced ferredoxin + thioredoxin disulfide = 2 oxidized ferredoxin + thioredoxin + 2 H(+).
-!- The enzyme contains a [4Fe-4S] cluster and internal disulfide. -!- It forms a mixed disulfide with thioredoxin on one side, and docks ferredoxin on the other side, enabling two one-electron transfers. -!- The reduced thioredoxins generated by the enzyme activate the Calvin cycle enzymes EC 3.1.3.11, EC 3.1.3.37 and EC 2.7.1.19 as well as other chloroplast enzymes by disulfide reduction.
