Glutathione reductase (GR) also known as glutathione-disulfide reductase (GSR) is an enzyme that in humans is encoded by the GSR gene.Glutathione reductase (EC 1.8.1.7) catalyzes the reduction of glutathione disulfide to the sulfhydryl form glutathione (), which is a critical molecule in resisting oxidative stress and maintaining the reducing environment of the cell.
The ratio of reduced glutathione to oxidized glutathione within cells is a measure of cellular oxidative stress [17] [10] where increased GSSG-to-GSH ratio is indicative of greater oxidative stress. In the reduced state, the thiol group of cysteinyl residue is a source of one reducing equivalent. Glutathione disulfide (GSSG) is thereby generated.
Glutathione disulfide (GSSG) is a disulfide derived from two glutathione molecules. [1] In living cells, glutathione disulfide is reduced into two molecules of glutathione with reducing equivalents from the coenzyme NADPH. This reaction is catalyzed by the enzyme glutathione reductase. [2]

Together these components compose the glutathione system. [6] Like thioredoxin, which functions in a similar way, glutaredoxin possesses an active centre disulfide bond. [7] It exists in either a reduced or an oxidized form where the two cysteine residues are linked in an intramolecular disulfide bond.
It is also the major transport form of reduced sulfur in plants. Roots likely largely depend for their reduced sulfur supply on shoot/root transfer of glutathione via the phloem, since the reduction of sulfur occurs predominantly in the chloroplast. Glutathione is directly involved in the reduction and assimilation of selenite into selenocysteine.
