It catalyzes the 2-electron reduction of the disulfide of thioredoxin (Trx) with electrons from ferredoxin (Fd). It contains a catalytic subunit (FTR-C) and variable subunit (FTR-V). Ferredoxin thioredoxin reductase catalytic and variable subunits with ferredoxin I with Fe2S2 and Fe4S4. Fe2S2 binding site. Fe4S4 binding site (2pvg). Water molecules are shown as red spheres.
