It converts an electron signal (photoreduced ferredoxin) to a thiol signal (reduced thioredoxin) in the regulation of enzymes by reduction of specific disulfide groups. Catalyzes the light-dependent activation of several photosynthetic enzymes (By similarity).[PIRNR:PIRNR000260] [FTRV_SYNY3] FTR is a [4Fe-4S] protein playing a central role in the ferredoxin/thioredoxin regulatory chain.

Publication Abstract from PubMed Light generates reducing equivalents in chloroplasts that are used not only for carbon reduction, but also for the regulation of the activity of chloroplast enzymes by reduction of regulatory disulfides via the ferredoxin:thioredoxin reductase (FTR) system. FTR, the key electron/thiol transducer enzyme in this pathway, is unique in that it can reduce disulfides by an iron-sulfur cluster, a property that is explained by the tight contact of its active-site disulfide and the iron-sulfur center. The thin, flat FTR molecule makes the two-electron reduction possible by forming on one side a mixed disulfide with thioredoxin and by providing on the opposite side access to ferredoxin for delivering electrons.
