conditions. A second electron transfer from a second molecule of NADPH reduces the active site tihiol bonds with one Cys residue stabilized by an interaction with FAD (Step B). The selenolate anion then attacks the disulfide bonds of Trx and the resulting enzyme-Trx mixed selenenylsulfide (Step C), which is then subsequently attacked by the neighboring Cys residue to regenerate the selenenylsulfide (Step D). This selenenylsulfide is then reduced by the active-site thiolate from the other subunit (Step E). Adapted from Zhong et al. Consistent with findings that (2,2‘:6‘,2‘‘-terpyridine)platinum(II) complexes inhibit human TrxR.

The Trx system exists in all living cells and has an evolutionary history tied to DNA as a genetic material, defense against oxidative damage due to oxygen metabolism, and redox signaling using molecules like hydrogen peroxide and nitric oxide.

Furthermore two mutations in the TrxR2 gene are found in patients diagnosed with DCM and not in a control population. It is hypothesized that the pathological impact of these mutations is an impaired ability to control oxidative damage in

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

Starting from the completely oxidized form, the reaction begins with the reduction of the selenenylsulfide to the selenolate anion (Se(-1)) with electrons received from NADPH via FAD (Step A). Due to the low pKa value of the selenol the selenolate anion is the predominant form under physiological
