ENZYME entry: EC 1.8.7.2

Accepted Name
ferredoxin:thioredoxin reductase.
Reaction catalysed
[thioredoxin]-disulfide + 2 H(+) + 2 reduced [2Fe-2S]-[ferredoxin] <=> [thioredoxin]-dithiol + 2 oxidized [2Fe-2S]-[ferredoxin]
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.
