Function
function
Catalytic subunit of the ferredoxin-thioredoxin reductase (FTR), which catalyzes the two-electron reduction of thioredoxins by the electrons provided by reduced ferredoxin.
Catalytic activity
- [thioredoxin]-disulfide + 2 reduced [2Fe-2S]-[ferredoxin] + 2 H+ = [thioredoxin]-dithiol + 2 oxidized [2Fe-2S]-[ferredoxin]
