ENZYME entry: EC 1.8.7.2
Accepted Name |
Ferredoxin:thioredoxin reductase.
|
Reaction catalysed |
2 reduced ferredoxin + thioredoxin disulfide <=> 2 oxidized ferredoxin + thioredoxin + 2 H(+) |
Cofactor(s) |
Iron-sulfur.
|
Comment(s) |
- 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.
