Protein Domain : Ferredoxin thioredoxin reductase, alpha chain IPR004207

Type	Domain
Description	Ferredoxin thioredoxin reductase is a [4FE-4S] protein which plays an important role in the ferredoxin/thioredoxin regulatory chain. It converts an electron signal (photoreduced ferredoxin) to a thiol signal (reduced thioredoxin), regulating enzymes by reduction of specific disulphide groups. It catalyses the light-dependent activation of several photosynthesis enzymes. Ferredoxin thioredoxin reductase is a heterodimer of subunit a and subunit b. Subunit a is the variable subunit, and b is the catalytic chain [, ]. This entry represents a domain found in the variable or alpha subunit of this group of ferredoxin thioredoxin reductases predominantly found in cyanobacteria and plants. In some members this is the only domain present in the protein, while in others it is located at the C-terminal end of the sequence.
