glutathione reductase

Also found in: Dictionary, Acronyms, Encyclopedia, Wikipedia.

glu·ta·thi·one re·duc·tase

an enzyme that catalyzes the reaction of glutathione disulfide with NADH (or NADPH), forming two glutathiones and NAD+ (or NADP+); involved in many redox reactions; a deficiency can cause hemolysis with oxidative stress.

Reduced status of antioxidants such as glutathione and ascorbic acid is maintained by glutathione reductase (GR), monodehydroascorbate reductase (MDAR) and dehydroascorbate reductase (DHAR), using NADPH as areducing agent (Apel and Hirt, 2004; Bhattacharjee, 2005; Gill andTuteja, 2010).

Glutathione reacts rapidly and needs to be exposed inside the yeast cell to enzyme glutathione reductase to be reactivated.
The product of glutathione oxidation, oxidized glutathione, is known to be toxic and is rapidly converted back to glutathione by the enzyme glutathione reductase (Cotran et al., 1989).
Glutathione peroxidase (GPX) and glutathione reductase enzyme action is related to glutathione reduction and oxidation (Bakalli et al., 1995).
GSH-dependent detoxification involves glutathione peroxidase (GSHx), which has a pivotal role in the elimination of hydrogen and organic peroxides and leads to the formation of oxidized glutathione but is reduced back to its thiol form (GSH) by glutathione reductase (GSHr), leading to the consumption of NADPH, which is chiefly formed by pentose phosphate pathway.
