glucose 6- phosphate dehydrogenase from streptomyces aureofaciens was purified andinactivated by pyridoxal 5′-phosphate (plp). the inactivation was a pseudo-first order and time-dependentreaction. complete inactivation was achieved at 0.2mm plp within 16 minutes. the type of inhibition wascompetitive with respect to glucose 6- phosphate. spectral characteristics of plp-enzyme complexcorresponde...

interaction of glucose 6-phosphate dehydrogenase from s. aureofaciens with nad+, nadp+and glucose 6-phosphate were investigated using different fluorescent probes. binding of nad+, nadp+and s-nadph to the native enzyme quenched intrinsic protein fluorescence by 100%, 10% and 21%,respectively, from which kd values of nad+ (6.5 mm), nadp+ (92.0 μm) and s-nadph (122.0 μm)were calculated. binding o...

Background: Glucose-6-Phosphate dehydrogenase (G6PD) deficiency is an Xlinked recessive disorder expressed mostly in males. Prevalence of G6PD deficiency varies in different parts of the world’s according to ethnic variation. The incidence varies among different countries in the world and surveys report rates of less than 1% to 35%. The prevalence of G6PD deficiency in the Arab world has variou...

Background: Storage of platelet concentrates (PCs) at room temperature (20-24°C) limits its storage time to 5 Background: Glucose-6-phosphate dehydrogenase (G6PD) deficiency is the most common inherited enzyme deficiency of the human red blood cells . Most of G6PD deficient individuals are asymptomatic, but acute hemolytic anemia may be presented with nausea, vomiting, abdominal pain, headache,...

a survey was set up to study the problem of g-6 _ pd deficiency in iran. the deficient subjects underwent a detailed haematological investigation, and their geneological tree was drawn and studied. a registry has been started to enable a follow_up of the deficients revealed by the survey. it is proposed to increase the size and scope of the survey gradual stages so that a statistical analysis o...

background and aims: glucose-6-phosphate dehydrogenase (g6pd) is the first enzyme in the route of pentose phosphate metabolism. this route fulfills an effective role in removing oxidant metabolites. deficiency of this enzyme causes decline in energy regeneration of red blood cells and hemolysis. in this study, application of fluorescence staining method in diagnosing the frequency of g6pd defic...
