Description
In enzymology, a phosphogluconate dehydrogenase (decarboxylating) (EC 1.1.1.44) is an enzyme that catalyzes the chemical reaction:6-phospho-D-gluconate + NADP+↔ D-ribulose 5-phosphate + CO2 + NADPH. Thus, the two substRates of this enzyme are 6-phospho-D-gluconate and NADP+, whereas its 3 products are D-ribulose 5-phosphate, CO2, and NADPH. This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD+ or NADP+ as acceptor.
Abbr
6-Phosphogluconic Dehydrogenase, Native (Yeast)
Applications
6-phosphoglyconic dehydrogenase (6PGD) is a key enzyme in the oxidative portion of the hexose monophosphate shunt. It is specific for oxidized nicotinamide adenine dinucleotide phosphate (NADP+). 6-phosphogluconate dehydrogenase is involved in the production of ribulose 5-phosphate, which is involved in nucleotide synthesis and the pentose phosphate pathway by generating NADPH. 6-phosphogluconate dehydrogenase is used to study nucleotide synthesis, glucose metabolism, and the protection of cells from oxidative damage.
