>gnl|CDD|48565 cd03016, PRX_1cys, Peroxiredoxin (PRX) family, 1-cys PRX subfamily; composed of PRXs containing only one conserved cysteine, which serves as the peroxidatic cysteine. They are homodimeric thiol-specific antioxidant (TSA) proteins that confer a protective role in cells by reducing and detoxifying hydrogen peroxide, peroxynitrite, and organic hydroperoxides. As with all other PRXs, a cysteine sulfenic acid intermediate is formed upon reaction of 1-cys PRX with its substrates. Having no resolving cysteine, the oxidized enzyme is resolved by an external small-molecule or protein reductant such as thioredoxin or glutaredoxin. Similar to typical 2-cys PRX, 1-cys PRX forms a functional dimeric unit with a B-type interface, as well as a decameric structure which is stabilized in the reduced form of the enzyme. Other oligomeric forms, tetramers and hexamers, have also been reported. Mammalian 1-cys PRX is localized cellularly in the cytosol and is expressed at high levels in brain, eye, testes and lung. The seed-specific plant 1-cys PRXs protect tissues from reactive oxygen species during desiccation and are also called rehydrins.. Length = 203
