Thioredoxin reductases are enzymes that catalyze the reduction of thioredoxin and hence they are a central component in the thioredoxin system. Together with thioredoxin (Trx) and NADPH this system's most general description is as a system for reducing disulfide bonds in cells. Electrons are taken from … See more Thioredoxin reductases (TR, TrxR) (EC 1.8.1.9) are enzymes that reduce thioredoxin (Trx).

The active sites of the peroxiredoxins feature a redox-active cysteine residue (the peroxidatic cysteine), which undergoes oxidization to a sulfenic acid by the peroxide substrate. The recycling of the sulfenic acid back to a thiol is what distinguishes the three enzyme classes. 2-Cys peroxiredoxins are reduced by thiols such as thioredoxins, thioredoxin-like proteins, or possibly glutathione, whereas the 1-Cys enzymes may be reduced by ascorbic acid or glutathione in the pr… WebJan 18, 2000 · Whether reduction in the absence of GILT is caused by a constitutive thiol reductase is unknown.
