| ribonucleotide reductase | A protein complex that converts ribonucleotide diphosphates (NDPs) such as ADP and CDP to 2'-deoxyribonucleotide diphosphates (dNDPs) such as dADP and dCDP. This complex requires thioredoxin, thioredoxin reductase, and NADPH. It is crucial for DNA synthesis. (05 Mar 2000) |

| 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) |

Synonyms : Ribonucleotide Reductase, Reductase, Ribonucleotide, Reductases, Ribonucleotide
| ribonucleotide reductase |
The enzyme in all organisms that catalyzes the conversion of nucleosides to deoxynucleosides.
