Glucose-6-phosphate dehydrogenase has been purified lOOO-fold from pig liver. This enzyme exists as an active dimer of molecular weight 133,000 and an inactive monomer of molecular weight 67,500. The pH of maximum activity is 8.5 and the ionic strength maximum is 0.1 to 0.5 M. Glucose-6-phosphate dehydrogenase is highly specific for NADP+ and glucose B-phosphate. Apparent K, values of 3.6 pM an...
Homogeneous biosynthetic sn-glycerol-3-phosphate dehydrogenase (EC 1.1.1.8) of Escherichia coli was potently inhibited by palmitoyl-CoA and other long chain acyl-CoA thioesters. The concentration dependence of this inhibition was not cooperative. Enzyme activity was inhibited 50% at 1 PM palmitoyl-CoA; thus, this inhibition occurred at concentrations below the critical micellar concentration of...
A patient with primary thrombocythemia, who was heterozygous for glucose-6-phosphate dehydrogenase deficiency (GdB/GdMed), was investigated to test for the clonal origin of this myeloproliferative disorder. In order to assess somatic cell mosaicism in various tissues, we have made use of the different rate of utilization of 2-deoxyglucose-6-phosphate, an analog of glucose-6-phosphate, by normal...
The metabolism of glucose was examined in several clinical isolates of Neisseria gonorrhoeae. Radiorespirometric studies revealed that growing cells metabolized glucose by a combination on the Entner-Doudoroff and pentose phosphate pathways. A portion of the glyceraldehyde-3-phosphate formed via the Entner-Doudoroff pathway was recycled by conversion to glucose-6-phosphate. Subsequent catabolis...
Abstract Background and objectives: Glucose-6-phosphate dehydrogenase (G6PD) is an enzyme in the pentose phosphate pathway. G6PD deficiency (an X-linked recessive hereditary disease) is an inherited condition affecting approximately 3% of the people globally. This deficiency can cause hemolytic anemia and jaundice in neonates. The goal of this study is to detect the prevalence of G6PD deficienc...
The interconversion of glycerol 3-phosphate and dihydroxyacetone phosphate by glycerol-3-phosphate dehydrogenases provides a link between carbohydrate and lipid metabolism and provides Saccharomyces cerevisiae with protection against osmotic and anoxic stress. The first structure of a glycerol-3-phosphate dehydrogenase from S. cerevisiae, GPD1, is reported at 2.45 Å resolution. The asymmetric u...
