Glucose-6-phosphate dehydrogenase (G6PD) deficiency is the most common enzymatic disorder in humans and appears to be protective against falciparum severe malaria. Controversially, it is also thought that Plasmodium vivax has driven the recent selection of G6PD alleles. We use an experimental approach to determine whether G6PD-MahidolG487A variant, a widespread cause of severe G6PD deficiency i...

glucose-6-phosphate dehydrogenase (g6pd) in humans is in x-linked disorder, housekeeping enzyme and vital for the survival of every cell. it catalyses the oxidation of glucose-6-phosphate to 6-phospho gluconat in the first committed step of the pentose phosphate pathway, which provides cells with pentoses and reducing power in the form of nadph. nadph is required to protect the cells against ox...

Glucose-6-phosphate dehydrogenase (G6PD) deficiency is probably the most common disease-producing genetic polymorphism of humans. Virtually all G6PD-deficient Africans show the G6PD A- phenotype, an electrophoretically rapid, deficient enzyme. The recently acquired ability to identify the point mutations producing the different variants has given us new insights into the population genetics of ...

Isogenic lines, in which chromosomes sampled from natural populations of C. melanogaster are substituted into a common genetic background, were used to detect and partially characterize autosomal factors that affect the activities of the two pentose phosphate pathway enzymes, glucose 6-phosphate dehydrogenase (G6PD) and 6-phosphogluconate dehydrogenase (6PGD). The chromosome 3 effects on G6PD a...

INTRODUCTION The glucose-6-phosphate dehydrogenase (G6PD) fluorescent spot test (FST) is a useful screening test for G6PD deficiency, but is unable to detect heterozygote G6PD-deficient females. We sought to identify whether reporting intermediate fluorescence in addition to absent and bright fluorescence on FST would improve identification of mildly deficient female heterozygotes. METHODS A ...

Glucose-6-phosphate dehydrogenase (G6PD) deficient subjects are vulnerable to oxidative stress. Quercetin, a flavonoids, has been employed as a potent oxygen-free radical scavenger in order to assess the protective effects of quercetin against H2O2-induced oxidative damage in G6PD-deficient and normal human erythrocytes. Erythrocytes of G6PD-deficient (n = 10) and normal (n = 10) subjects were ...

glucose-6-phosphate dehydrogenase (g6pd) enzyme catalyses the first step in pentose phosphate pathway (conversion of glucose-6-phosphat to 6-phospho gluconat) which provides cells with pentoses and reduction power in the form of nadph. in the present study we have analyzed the g6pd gene mutations in 76 patients with a history of favism in khorasan province in iran. dna samples were analyzed for...

Glucose-6-phosphate dehydrogenase (G6PD) deficiency is one of the most common hereditary enzymatic disorders in human, increases the vulnerability of erythrocytes to oxidative stress. It is also characterized by remarkable molecular and biochemical heterogeneity. According to previous investigations, G6PD Cosenza (G1376C) is a common G6PD mutation in some parts of . Therefore in the present stu...

Glucose-6-phosphate dehydrogenase (G6PD, EC1.1.1.49) is expressed in all tissues where it is the first and rate-limiting enzyme of the pentose phosphate pathway (PPP) [1] that consists of the oxidative and non-oxidative branches and usually works at 1–2% of its maximal potential in healthy subjects due to the high level of nicotinamide adenine dinucleotide phosphate (NADPH). The G6PD gene is wi...

Clones of 32 strains of Trichomonas vaginalis isolated from patients attending a venereal diseases clinic were compared among themselves and with authentic Pentatrichomonas hominis on the basis of their isoenzyme patterns for eight enzymes by thin-layer starch-gel electrophoresis. The enzymes examined were: glucose phosphate isomerase (GPI); phosphoglucomutase (PGM); malic enzyme (NADP+) (ME); ...
