>TIGR01292 TRX_reduct thioredoxin-disulfide reductase; InterPro: IPR005982 Reactive oxygen species (ROS) are known mediators of intracellular signaling cascades. Excessive production of ROS may, however, lead to oxidative stress, loss of cell function, and ultimately apoptosis or necrosis. A balance between oxidant and antioxidant intracellular systems is hence vital for cell function, regulation, and adaptation to diverse growth conditions. Thioredoxin reductase in conjunction with thioredoxin is a ubiquitous oxidoreductase system with antioxidant and redox regulatory roles. Thioredoxin reductase (1.8.1.9 from EC) reduces oxidised thioredoxin in the presence of NADPH. Reduced thioredoxin serves as an electron donor for thioredoxin peroxidase which consequently reduces H_2O_2 to H_2O. In mammals, extracellular forms of Trx also have cytokine-like effects. Mammalian TrxR has a highly reactive active site selenocysteine residue resulting in a profound reductive capacity, reducing several substrates in addition to Trx .; GO: 0004791 thioredoxin-disulfide reductase activity, 0019430 removal of superoxide radicals, 0005737 cytoplasm.
