Dehydrogenation of the phosphonate analogue of glucose 6-phosphate by glucose 6-phosphate dehydrogenase.
6,7 -Dideoxy-alpha-D-gluco-heptose 7-phosphonic acid, the isosteric phosphonate analogue of glucose 6-phosphate, was synthesized in six steps from the readily available precursor benzyl 4,6-O-benzylidene-alpha-D-glucopyranoside. The analogue is a substrate for yeast glucose 6-phosphate dehydrogenase, showing Michaelis-Menten kinetics at pH7.5 and 8.0. At both pH values the Km values of the anal...
متن کاملGlucose-6-Phosphate Dehydrogenase
Description Glucose-6-Phosphate Dehydrogenase (G6PD) deficiency is the most common human enzyme deficiency that mainly affects the red blood cells (RBCs). A defect in G6PD enzyme leads to the destruction of premature RBCs causing hemolytic anemia because the body can not compensate the destroyed RBCs. Thus, the affected individuals show jaundice (paleness, yellowing of the skin and whites of th...

6,7-Dideoxy-D-gluco-heptonic-7-phosphonic acid, the isosteric phosphonate analogue of gluconate 6-phosphate, was prepared by incubation of the corresponding analogue of glucose 6-phosphate with glucose 6-phosphate dehydrogenase and NADP+ in the presence of an enzyme NADPH-NADP+ recycling system. The analogue of gluconate 6-phosphate is a substrate for yeast gluconate 6-phosphate dehydrogenase, ...
متن کاملGlucose-6-Phosphate Dehydrogenase Deficiency and Neonatal Hyperbilirubinemia
Background: Jaundice is affecting over 60-80 percent of neonates in the first week of life. Glucose-6-phosphate dehydrogenase (G6PD) deficiency, which is an important cause of pathologic hyperbilirubinemia, can lead to hemolytic anemia, jaundice and kernicterus. The present study was performed to determine the prevalence of G6PD deficiency among icteric neonates in Shirvan, Iran. Methods: This...
