<unk>  <unk>  is a cytosolic enzyme in the pentose<unk>  pathway (see image), a metabolic pathway that supplies reducing energy to cells (such as erythrocytes) by maintaining the level of the co-enzyme nicotinamide adenine dinucleotide<unk>  (NADPH). The NADPH in turn maintains the level of glutathione in these cells that helps protect the red blood cells against oxidative damage. Of greater quantitative importance is the production of NADPH for tissues actively engaged in biosynthesis of fatty acids and/or isoprenoids, such as the liver, mammary glands, adipose tissue, and the adrenal glands.<unk>  is stimulated by its substrate NADP+. The usual ratio of NADPH/NADP+ in the cytosol of tissues engaged in biosyntheses is about 100/1. Increased utilization of NADPH for fatty acid biosynthesis will dramatically increase the level of NADP+, thus stimulating<unk>  to produce more NADPH.<unk>  converts<unk> -6-phosphate into<unk> -phosphoglucono-δ-lactone and is the rate-limiting enzyme of the pentose<unk>  pathway.<unk>  deficiency is very common worldwide, and cause acute hemolytic anemia in the presence of simple infection, ingestion of fava beans, or reaction with certain medicines, AAA, antibiotics, antipyretics, and antimalarials.<unk>  is remarkable for its genetic diversity. Many variants of<unk> , mostly produced from missense mutations, have been described with wide ranging levels of enzyme activity and associated clinical symptoms. Two transcript variants encoding different isoforms have been found for this gene.
Glucose-6-phosphate dehydrogenase
Aldehyde dehydrogenase
D-amino acid dehydrogenase
Phosphoglucomutase
Succinate dehydrogenase
Oxoglutarate dehydrogenase
Formate dehydrogenase
Transaminase
