Reaction:

2 glutathione + NADP⁺ = glutathione disulfide + NADPH + H⁺

Glossary:

The term ’oxidized glutathione’ has been replaced by the term ’glutathione disulfide’ as the former is ambiguous. S,S′-Biglutathione may also be used to refer to this compound.

Other name(s):

glutathione reductase; glutathione reductase (NADPH); NADPH-glutathione reductase; GSH reductase; GSSG reductase; NADPH-GSSG reductase; glutathione S-reductase; NADPH:oxidized-glutathione oxidoreductase

Systematic name:

glutathione:NADP⁺ oxidoreductase

Comments:

A dimeric flavoprotein (FAD); activity is dependent on a redox-active disulfide in each of the active centres.
