| lipoamide reductase | <enzyme> An enzyme oxidizing dihydrolipoamide at the expense of NAD+; completes the oxidative decarboxylation of pyruvate; a part of several enzyme complexes (e.g., alpha-ketoglutarate dehydrogenase complex). Decreased activity leads to neuronal loss in brain resulting in psychomotor retardation. Synonym: coenzyme factor, lipoamide dehydrogenase, lipoamide reductase (NADH), lipoyl dehydrogenase. (05 Mar 2000) |

| pyruvate dehydrogenase (lipoamide) | An oxidoreductase catalyzing conversion of pyruvate and (oxidised) lipoamide to CO2 and S6-acetyldihydrolipoamide in two successive reactions: the first between pyruvate and thiamin pyrophosphate to yield CO2 and alpha-hydroxyethylthiamin pyrophosphate (active pyruvate); the second between the last named and lipoamide to regain the thiamin pyrophosphate and yield S6-acetylhydrolipoamide. Compare: alpha-ketodecarboxylase. (05 Mar 2000) |

| pyruvate dehydrogenase (lipoamide)-phosphatase | <enzyme> (pyruvate dehydrogenase (lipoamide))-phosphate phosphohydrolase. A mitochondrial enzyme that catalyses the hydrolytic removal of a phosphate on a specific seryl hydroxyl group of pyruvate dehydrogenase, reactivating the enzyme complex. Registry number: EC 3.1.3.43 (12 Dec 1998) |
| (pyruvate dehydrogenase (lipoamide))kinase | Registry number: EC 2.7.1.99 Synonym: pyruvate dehydrogenase kinase (26 Jun 1999) |

| lipoamide dehydrogenase | <enzyme> An enzyme that regenerates lipoamide from the reduced form dihydrolipoamide. (18 Nov 1997) |
| lipoamide disulfide | Oxidised lipoic acid in amide combination with the &vepsilon;-amino group of an l-lysyl residue of pyruvic acid dehydrogenase. (05 Mar 2000) |
| acetoacetyl-CoA reductase | An oxidoreductase catalyzing interconversion of a 3-oxoacyl-CoA and NADPH, and the corresponding d-3-hydroxyacyl-CoA, and NADP+. A step in fatty acid synthesis. (05 Mar 2000) |

| acryloyl-CoA reductase | <enzyme> Clostridium kluyveri enzyme; contains fmn, ferredoxin, and flavodoxin; can act as electron donors Registry number: EC 1.3.99.- Synonym: acryloyo-coenzyme a reductase (26 Jun 1999) |
| aflatoxin B1 aldehyde reductase | <enzyme> Catalyses the conversion of the dialdehydic form of aflatoxin b1-dihydrodiol to the dialcohol form Registry number: EC 1.1.1.- Synonym: aflatoxin b1-aldehyde reductase, afb1-ar (26 Jun 1999) |
| aflatoxin B1 reductase | <enzyme> Reduces the cyclopentenone ring of aflatoxin b1 to aflatoxicol; requires NADPH as cofactor Registry number: EC 1.1.1.- (26 Jun 1999) |
| aflatoxin G2a reductase | <enzyme> Has broad substrate specificity in cell-free extracts from aspergillus parasiticus; versicolorin a hemiacetal is reduced to versicolorin c; 17-hydroxy-16,17-dihydrosterigmatocystin is reduced to a 14,17-hydrated derivative; aflatoxin g2a is converted to a 13,16-hydrated derivative of afg2 Registry number: EC 1.1.1.- (26 Jun 1999) |
| aldehyde reductase | <enzyme> An enzyme that catalyses reversibly the oxidation of an aldose to an alditol. It possesses broad specificity for many aldoses. Chemical name: Alditol:NAD(P)+ 1-oxidoreductase Registry number: EC 1.1.1.21 (12 Dec 1998) |
| aldose reductase | A polyol dehydrogenase (NADP+);an oxidoreductase that reversibly converts aldoses to alditols (e.g., glucose to sorbitol) with NADPH as hydrogen donor. An important step in the metabolism of sorbitol and in the formation of diabetic cataracts. See: d-sorbitol-6-phosphate dehydrogenase. (05 Mar 2000) |
| aldose reductase inhibitor | <pharmacology> A class of drugs being studied as a way to prevent eye and nerve damage in people with diabetes. Aldose reductase is an enzyme that is normally present in the eye and in many other parts of the body. It helps change glucose (sugar) into a sugar alcohol called sorbitol. Too much sorbitol trapped in eye and nerve cells can damage these cells, leading to retinopathy and neuropathy. Drugs that prevent or slow (inhibit) the action of aldose reductase are being studied as a way to prevent or delay these complications of diabetes. (09 Oct 1997) |
