| maltose dehydrogenase | <enzyme> Nad+ dependent Registry number: EC 1.1.1.- (26 Jun 1999) |
| gluconate 5-dehydrogenase | <enzyme> Catalyses conversion of gluconic acid to 5-ketogluconic acid; genbank x80019(gno) Registry number: EC 1.1.1.69 Synonym: gluconate-nadp 5-oxidoreductase, gno dehydrogenase, gno gene product (26 Jun 1999) |
| glucose-6-dehydrogenase deficiency | <biochemistry> An inherited condition that results in a deficiency in glucose-6-phosphate dehydrogenase. Particular drugs (sulphonamides) can exacerbate this problem. The result is haemolytic anaemia. (27 Sep 1997) |
| glucose-6-phosphate dehydrogenase | <enzyme> An NADP+ enzyme that catalyses the dehydrogenation (oxidation) of d-glucose-6-phosphate to 6-phospho-d-glucono-d-lactone, this reaction initiating the Dickens shunt. Deficiency of this enzyme is the commonest disease-causing enzyme defect in humans affecting an estimated 400 million people. The gene for this enzyme is on the X chromosome. Males with the enzyme deficiency develop haemolytic anaemia when red blood cells are exposed to oxidant drugs such as the antimalarial primaquine, the sulfonamide antibiotics or sulfones, naphthalene moth balls, or fava beans. Synonym: Robison ester dehydrogenase, Zwischenferment. Acronym: G6PD (12 Sep 2002) |
| glucose-6-phosphate dehydrogenase deficiency | A deficiency of glucose-6-phosphate dehydrogenase, an enzyme important for maintaining cellular concentrations of reduced nucleotides. Deficiency of this enzyme is the commonest disease-causing enzyme defect in humans affecting an estimated 400 million people. The gene for this enzyme is on the X chromosome and there are various polymorphic forms. Males with the enzyme deficiency develop haemolytic anaemia when red blood cells are exposed to oxidant drugs such as the antimalarial primaquine, the sulfonamide antibiotics or sulfones, naphthalene moth balls, or fava beans. It can also cause anaemia of the newborn, and chronic nonspherocytic haemolytic anaemia. Inheritance: X-linked. (12 Sep 2002) |
| glucose dehydrogenase | <enzyme> Converts beta-d-glucose to d-glucono-d-lactone, transferring hydrogen to NAD+ or NADP+. Compare: glucose oxidase. (05 Mar 2000) |
| glucosephosphate dehydrogenase | <enzyme> Chemical name: D-Glucose-6-phosphate:NADP+ 1-oxidoreductase Registry number: EC 1.1.1.49 (12 Dec 1998) |
| glucosephosphate dehydrogenase deficiency | A disease-producing enzyme deficiency subject to many variants, some of which cause a deficiency of enzyme activity in erythrocytes, leading to haemolytic anaemia. (12 Dec 1998) |
| glutamate dehydrogenase | <enzyme> An enzyme that catalyses the conversion of l-glutamate and water to 2-oxoglutarate and nh3 in the presence of NAD+. Chemical name: L-Glutamate:NAD+ oxidoreductase (deaminating) Registry number: EC 1.4.1.2 (12 Dec 1998) |
| glutamate dehydrogenase (NADP+) | <enzyme> An enzyme that catalyses the conversion of l-glutamate, h2o, and NADP+ to 2-oxoglutarate, nh3, and NADPH. Chemical name: L-Glutamate:NADP+ oxidoreductase (deaminating) Registry number: EC 1.4.1.4 (12 Dec 1998) |
| glutamate-saemialdehyde dehydrogenase | <enzyme> Converts 5-glutamyl phosphate to glutamate 5-saemialdehyde in the presence of NADPH; see also glutamic-gamma-saemialdehyde dehydrogenase which catalyses the oxidation of 1-pyrroline-5-carboxylate to l-glutamate in the presence of nad Registry number: EC 1.2.1.41 Synonym: beta-glutamylphosphate reductase, glutamate 5-saemialdehyde dehydrogenase, gamma-glutamylphosphate reductase, proa gene product (26 Jun 1999) |
