Accepted name: glutathione amide reductase
Reaction: 2 glutathione amide + NAD+ = glutathione amide disulfide + NADH + H+
Other name(s): GAR
Systematic name: glutathione amide:NAD+ oxidoreductase
Comments: A dimeric flavoprotein (FAD). The enzyme restores glutathione amide disulfide, which is produced during the reduction of peroxide by EC (glutathione amide-dependent peroxidase), back to glutathione amide (it catalyses the reaction in the opposite direction to that shown). The enzyme belongs to the family of flavoprotein disulfide oxidoreductases, but unlike other members of the family, which are specific for NADPH, it prefers NADH [1].
