Description générale

Glucose-6-phosphate dehydrogenase (G6PD) is an X-linked essential enzyme that protects cells from oxidative stress, particularly red blood cells.

Application

Glucose-6-phosphate dehydrogenase was used to study atypical glycolysis in Clostridium thermocellum.

Actions biochimiques/physiologiques

Glucose-6-phosphate dehydrogenase (G6PD) catalyzes the conversion of glucose-6-phosphate to 6-phosphogluconolacetone as the first step in the pentose phosphate pathway.

Cofactor specificities of glycolytic enzymes in Clostridium thermocellum were studied with cellobiose-grown cells from batch cultures. Intracellular glucose was phosphorylated by glucokinase using GTP rather than ATP. Although phosphofructokinase typically uses ATP as a phosphoryl donor, we found only pyrophosphate

Orexin-A (a glucose-sensing neuropeptide in the hypothalamus) and brain-derived neurotrophic factor (BDNF; a member of the neurotrophin family) play roles in many physiologic functions, including regulation of glucose metabolism. We previously showed that the development of postischemic glucose intolerance is

Psychrophilic organisms have evolved a number of modifications of cellular structures to survive in the cold environment; among them it is worth noting an increased efficiency of enzymes at lower temperatures. Glucose-6-phosphate dehydrogenase (G6PDH; EC 1.1.1.49) was purified and characterised

During initial development, both X chromosomes are active in females, and one of them must be silenced at the appropriate time in order to dosage compensate their gene expression levels to male counterparts. Silencing involves epigenetic mechanisms, including histone deacetylation.
