Phosphogluconolactone
6-Phosphogluconolactonase (EC 3.1.1.31, 6PGL, PGLS, systematic name 6-phospho-D-glucono-1,5-lactone lactonohydrolase) is a cytosolic enzyme found in all organisms that catalyzes the hydrolysis of 6-phosphogluconolactone to 6-phosphogluconic acid in the oxidative phase of the pentose phosphate pathway: 6-phospho-D-glucono-1,5-lactone + H2O = 6-phospho-D-gluconate Web【产品介绍】： G6PDi-1 is a reversible and noncompetitive inhibitor of glucose-6-phosphate dehydrogenase (G6PDH; IC50 = 0.07 µM), the enzyme that converts G6P to 6-phosphogluconolactone using NADP+ as a cofactor in the first step of the pentose phosphate pathway.1 G6PDi-1 (10 and 50 µM) reduces NADPH levels in a variety of …

WebApr 27, 2009 · While 6-phosphogluconolactone and 6-phosphogluconate are normally present in the host cytosol as intermediate metabolites in the mammalian PPP, the dephosphorylated versions of these metabolites are unlikely to be produced in mammalian cells. Our lab is currently investigating a potential role for these foreign metabolites in … 6-Phosphogluconolactone is an intermediate in the pentose phosphate pathway (PPP). In the PPP pathway, it is produced from glucose-6-phosphate by glucose-6-phosphate dehydrogenase. It is then converted to 6-Phosphogluconic acid by 6-phosphogluconolactonase.
