| phosphogalactoisomerase | <enzyme> An enzyme that catalyses the transfer of ump from udpglucose to galactose 1-phosphate, forming udpgalactose and glucose 1-phosphate. Deficiency in this enzyme is the major cause of galactosaemia. Chemical name: UDPglucose:alpha-D-galactose-1-phosphate uridylyltransferase Registry number: EC 2.7.7.12 (12 Dec 1998) |
| phosphoglucokinase | <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) |
| phosphoglucomutase | <enzyme> An enzyme that catalyses the conversion of alpha d-glucose 1-phosphate to alpha d-glucose-6-phosphate. Chemical name: alpha-D-Glucose 1,6-phosphomutase Registry number: EC 5.4.2.2 (12 Dec 1998) |
| phosphogluconate dehydrogenase | <enzyme> An enzyme of the oxidoreductase class that catalyses the reaction 6-phospho-d-gluconate and NADP+ to yield d-ribulose 5-phosphate, carbon dioxide, and NADPH. The reaction is a step in the pentose phosphate pathway of glucose metabolism. Chemical name: 6-Phospho-D-gluconate:NAD(P)+ 2-oxidoreductase Registry number: EC 1.1.1.43 (12 Dec 1998) |
| phosphogluconate pathway | <biochemistry> This oxidative pathway starts with glucose-6-phosphate andeventually results in the creation of pentose phosphates and NADPH. (09 Oct 1997) |
| phosphoglucosamine mutase | <enzyme> Catalyses the interconversion of glucosamine-6-phosphate and glucosamine-1-phosphate isomers; femr315 isolated from staphylococcus aureus Registry number: EC 5.4.2.- Synonym: glmm gene product, femr315 gene product (26 Jun 1999) |
| phosphoglucose isomerase | <enzyme> In glycolysis, phosphoglucose isomerase is the enzyme responsible for the isomerisation of glucose-6-phosphate, an aldose, toFructose 6-phosphate, a ketose. (09 Oct 1997) |
| phosphoglyceracetals | Generic term for glycerophospholipids in which the glycerol moiety bears a 1-alkenyl ether group (on rarer occasions, a 1-alkyl ether group); e.g., alk-1-enylglycerophospholipid; plasmalogens synthesis is reduced in disorders of the peroxisome. Synonym: phosphoglyceracetals. (05 Mar 2000) |
| phosphoglycerate | <biochemistry> The molecules 2 phosphoglycerate and 3 phosphoglycerate are intermediates in glycolysis. 3 phosphoglycerate is the precursor for synthesis of phosphatidic acid and diacyl glycerol, hence of phosphatidyl phospholipids. (31 Dec 1997) |
| phosphoglycerate dehydrogenase | <enzyme> Catalyses the oxidation of 3-phosphoglyceric acid to 3-phosphohydroxy pyruvate, which can be transaminated and then hydrolyzed to give serine; minor descriptor (75-85); on-line and index medicus search alcohol oxidoreductases (75-77) and carbohydrate dehydrogenases (78-85) Registry number: EC 1.1.1.95 Synonym: phosphoglycerate oxidoreductase, 3-phosphoglycerate-nad+ 2-oxidoreductase, 3-phosphoglycerate dehydrogenase, sera gene product (26 Jun 1999) |
| phosphoglycerate kinase | <enzyme> An enzyme catalyzing the transfer of a phosphate group from 3-phospho-d-glycerate in the presence of ATP to yield 3-phospho-d-glyceroyl phosphate and ADP. Chemical name: ATP-3-phospho-D-glycerate 1-phosphotransferase Registry number: EC 2.7.2.3 (12 Dec 1998) |
| phosphoglycerate mutase | <enzyme> An enzyme that catalyses the conversion of 2-phospho-d-glycerate to 3-phospho-d-glycerate. Chemical name: D-Phosphoglycerate 2,3-phosphomutase Registry number: EC 5.4.2.1 (12 Dec 1998) |
| phosphoglycerate permease | <chemical> (26 Jun 1999) |

HOCH2-CH(OPO3H2) COOH; 2-phosphoglyceric acid;the deprotonated form, 2-phosphoglycerate, is an intermediate in glycolysis. 3. H2O3POCH2-CH (OH)COOH; 3-phosphoglyceric acid;the deprotonated form, 3-phosphoglycerate, is an intermediate in glycolysis. (05 Mar 2000) |
