| mannosephosphate isomerase | <enzyme> An enzyme that catalyses the reversible conversion of d-mannose-6-phosphate to d-fructose-6-phosphate; a key step in the synthesis of mannose derivatives as well as the entry of mannose into the central pathways of carbohydrate metabolism. (05 Mar 2000) |

| glucose-6-phosphate isomerase | <enzyme> An enzyme that catalyses the reversible interconversion of glucose-6-phosphate and fructose-6-phosphate, and is a part of the glycolytic and gluconeogenic pathways. Deficiency of the enzyme, an autosomal recessive trait, results in liver glycogenesis and haemolytic anaemia. Chemical name: D-Glucose-6-phosphate ketol-isomerase Registry number: EC 5.3.1.9 (12 Dec 1998) |
| glucose isomerase | <enzyme> An isomerase enzyme which converts the sugar glucose into the sugar fructose. Fructose is a structural isomer of glucose. (09 Oct 1997) |
| glucose-phosphate isomerase | <enzyme> An enzyme that catalyses the reversible interconversion of d-fructose 6-phosphate and d-glucose-6-phosphate; a part of glycolysis and gluconeogenesis; glucosephosphate isomerase deficiency is an inherited disorder resulting in liver glycogenesis and haemolytic anaemia. Synonym: hexosephosphate isomerase, phosphohexomutase, phosphohexose isomerase. (05 Mar 2000) |
| glucosephosphate isomerase deficiency | <enzyme> An enzyme deficiency characterised by chronic nonspherocytic haemolytic anaemia; autosomal recessive inheritance. Synonym: phosphohexose isomerase deficiency. (05 Mar 2000) |
| retinaldehyde isomerase | <enzyme> Converts all-trans-retinal to 11-cis-retinal Registry number: EC 5.2.1.3 Synonym: retinal photoisomerase (26 Jun 1999) |
| retinal isomerase | <enzyme> Converts all-trans-retinal to 11-cis-retinal Registry number: EC 5.2.1.3 Synonym: retinal photoisomerase (26 Jun 1999) |
| retinol isomerase | <enzyme> Catalyses the isomerization of all trans-retinol to 11-cis-retinol in the dark; found in the pigment epithelium in the eye Registry number: EC 5.2.1.7 Synonym: retinoid isomerase (26 Jun 1999) |
| peptidyl prolyl cis trans isomerase | See: PPIase and immunophilin. (18 Nov 1997) |
| peptidylprolyl isomerase | <enzyme> An enzyme that catalyses the isomerization of proline residues within proteins. Chemical name: Peptidylproline cis-trans-isomerase Registry number: EC 5.2.1.8 (12 Dec 1998) |
| chalcone isomerase | <enzyme> Required for biosynthesis of flavonoid pigments and isoflavonoid phytoalexins; ubiquitous in all plants studied Registry number: EC 5.5.1.6 Synonym: chalcone-flavanone isomerase (26 Jun 1999) |
| ribose-5-phosphate isomerase | <enzyme> An enzyme catalyzing interconversion of d-ribose 5-phosphate and d-ribulose 5-phosphate; of importance in ribose metabolism and in the pentose phosphate pathway. Synonym: phosphopentose isomerase, phosphoriboisomerase. (05 Mar 2000) |
| 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) |
| phosphoheptose isomerase | <enzyme> Sedoheptulose-7-p is converted to d-glycero-d-manno-heptulose Registry number: EC 5.3.1.- (26 Jun 1999) |
| phosphohexose isomerase | <enzyme> An enzyme that catalyses the reversible interconversion of d-fructose 6-phosphate and d-glucose-6-phosphate; a part of glycolysis and gluconeogenesis; glucosephosphate isomerase deficiency is an inherited disorder resulting in liver glycogenesis and haemolytic anaemia. Synonym: hexosephosphate isomerase, phosphohexomutase, phosphohexose isomerase. (05 Mar 2000) |
