Application

Glucose-6-phosphate dehydrogenase from Leuconostoc mesenteroides has been used:

  • in the coupled spectrophotometric assay for PGI (F6P to G6P reaction)
  • to study the starch time course using Nicotiana tabacum leaves
  • to determine the glucose content in the root and stem samples of Quercus velutina Lam. saplings
  • to assay glucose using a starch sample of wild-type and transgenic Arabidopsis whole seedlings

Biochem/physiol Actions

Glucose-6-phosphate dehydrogenase (G6PD) catalyzes the conversion of glucose-6-phosphate to 6-phosphogluconolacetone as the first step in the pentose phosphate pathway.
Glucose-6-phosphate dehydrogenase (G6PD) is expressed in all tissues and produces the reduced form of nicotinamide adenine dinucleotide phosphate (NADPH), which aids the cells to prevent oxidative stress. Insufficiency of G6PD is an X-linked, hereditary genetic defect. It is caused due to a common mutation in the G6PD gene.

Unit Definition

One unit will oxidize 1.0 μmole of D-glucose 6-phosphate to 6-phospho-D-gluconate per min in the presence of NAD at pH 7.8 at 30 °C.

Phosphoglucoisomerase (PGI) isomerizes fructose 6-phosphate (F6P) and glucose 6-phosphate (G6P) in starch and sucrose biosynthesis. Both plastidic and cytosolic isoforms are found in plant leaves. Using recombinant enzymes and isolated chloroplasts, we have characterized the plastidic and cytosolic isoforms of

Cancer cells have long been recognized to exhibit unique bioenergetic requirements. The apoptolidin family of glycomacrolides are distinguished by their selective cytotoxicity towards oncogene-transformed cells, yet their molecular mechanism remains uncertain. We used photoaffinity analogs of the apoptolidins to identify

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

Protocols

To measure glucose-6-phosphate dehydrogenase activity, beta-nicotinamide adenine dinucleotide phosphate is used in a spectrophotometric rate determination assay at 340 nm.
