Phosphogluconate dehydrogenase
WebJul 14, 2008 · This C1 aldose (G6P) is oxidized by glucose-6-phosphate dehydrogenase to 6-phosphogluconate (6PG), and in turn 6-phosphogluconate dehydrogenase decarboxylates this β-keto carboxylic acid (6PG) to ribulose-5-phosphate (Ru5P). Ru5P is then isomerized to ribose-5-phosphate (R5P) by ribose-5-phosphate isomerase. Web3-PG competitively occupies the active site of phosphogluconate dehydrogenase (PGD), the rate-limiting enzyme in the PPP, resulting in impaired PGD function and the suppression of the PPP flux 17 .
