| mannose-1-phosphate guanylyltransferase | <enzyme> A transferase that catalyses the transfer of GDP to the mannose of mannose-1-phosphate. Consider also the bifunctional enzyme, phosphomannose isomerase-guanosine diphospho-d-mannose pyrophosphorylase; rfbm has similarity to long-chain, iron-containing alcohol dehydrogenases Registry number: EC 2.7.7.13 Synonym: GDPmannose phosphorylase, GDP mannose pyrophosphorylase, GTP-alpha-d-mannose-1-phosphate guanylyltransferase, GDP-mannose pyrophosphorylase, rfbm gene product, rfbm protein (26 Jun 1999) |

| mannose-6-phosphate | <biochemistry> Mannose derivative formed by phosphorylation in the Golgi complex of certain mannose residues on N glycan chains of lysosomal enzymes. Believed to function as targetting signal that causes entry of these enzymes to the lysosomes. The receptor (215 kD) is enriched in specialised pre lysosomes. (18 Nov 1997) |
| mannose-6-phosphate isomerase | <enzyme> An enzyme that catalyses the reversible isomerization of d-mannose-6-phosphate to form d-fructose-6-phosphate, an important step in glycolysis. Chemical name: D-Mannose-6-phosphate ketol isomerase Registry number: EC 5.3.1.8 (12 Dec 1998) |
| mannose-6-phosphate receptors | Receptors in Golgi apparatus to which newly synthesised proteins that are destined to enter lysosomes bind. (05 Mar 2000) |
| mannose-6-phosphate reductase | <enzyme> Involved in biosynthesis of mannitol in celery Registry number: EC 1.1.1.224 Synonym: manp reductase (26 Jun 1999) |
| geranylgeranyl phosphate kinase | <enzyme> Cytosolic enzyme that catalyses phosphorylation of geranylgeraniol phosphate to yield geranylgeranyl diphosphate; isolated from sulfolobus acidocaldarius Registry number: EC 2.7.4.- Synonym: ggp kinase (26 Jun 1999) |
| vidarabine phosphate | <chemical> An adenosine monophosphate analog in which ribose is replaced by an arabinose moiety. It is the monophosphate ester of vidarabine with antiviral and possibly antineoplastic properties. Pharmacological action: antimetabolites, antimetabolites, antineoplastic, antiviral agents. Chemical name: 9H-Purin-6-amine, 9-(5-O-phosphono-beta-D-arabinofuranosyl)- (12 Dec 1998) |
| glucose 1-phosphate | <biochemistry> Product of glycogen breakdown by phosphorylase. Converted to glucose 6 phosphate by phosphoglucomutase. (18 Nov 1997) |
| glucose-1-phosphate adenylyltransferase | <enzyme> Shrunken-2 (sh2) protein is a subunit of this enzyme Registry number: EC 2.7.7.27 Synonym: adpg synthetase, adpglucose pyrophosphorylase, ADP-glucose synthetase, shrunken-2 protein, shrunken gene product, ADP-glucose pyrophosphorylase, glgc gene product, bt2 gene product, brittle-2 gene product (26 Jun 1999) |
| glucose-1-phosphate kinase | <enzyme> An enzyme that, in the presence of ATP, catalyses the phosphorylation of d-glucose 1-phosphate to form d-glucose 1,6-bisphosphate and ADP; found in yeast and muscle; d-glucose 1,6-bisphosphate is a required cofactor of one of the enzymes in glycogenolysis. Synonym: glucose-1-phosphate kinase. (05 Mar 2000) |
| glucose-1-phosphate phosphodismutase | A phosphotransferase catalyzing the reversible transfer of a phosphate residue from one d-glucose 1-phosphate to another, yielding d-glucose 1,6-bisphosphate and d-glucose. This enzyme provides a crucial intermediate needed for glucose-phosphate isomerase. (05 Mar 2000) |
| glucose-1-phosphate uridylyltransferase | <enzyme> An enzyme that activates d-glucose by reacting d-glucose 1-phosphate with UTP, producing pyrophosphate and UDP glucose; a crucial step in glycogen biosynthesis. (05 Mar 2000) |
| glucose-6-phosphate | <biochemistry> Glucose 6-phosphate is a phosphomonoester of glucose that is formed by transfer of phosphate from ATP, catalysed by the enzyme hexokinase. It is an intermediate both of the glycolytic pathway (next converted to fructose 6 phosphate) and of the NADPH generating pentose phosphate pathway, formed from glucose via hexokinase. However it is not strictly a glycolytic intermediate and it is readily converted to glycogen or oxidized to NADPH. (10 Oct 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) |
