| NADH sennidin reductase | <enzyme> Reduces the dianthrones senniden or sennoside to rheinanthrone or 8-glucosylrheinanthrone respectively Registry number: EC 1.- Synonym: sennoside reductase (26 Jun 1999) |
|---|---|
| NADH tetrazolium reductase | <enzyme> Catalyses the reduction of tetrazolium compounds in the presence of NADH. Registry number: EC 1.6.- (12 Dec 1998) |
| NADH, NADPH oxidoreductases | <enzyme> A group of oxidoreductases that act on NADH or NADPH. In general, enzymes using NADH or NADPH to reduce a substrate are classified according to the reverse reaction, in which NAD+ or NADP+ is formally regarded as an acceptor. This subclass includes only those enzymes in which some other redox carrier is the acceptor. Registry number: EC 1.6. (12 Dec 1998) |
| NADH-cytochrome P-450 reductase | <enzyme> A component of the cytochrome p-450sca monoxygenase system Registry number: EC 1.6.2.- (26 Jun 1999) |
| NADH-dependent hydroxypyruvate reductase | <enzyme> Photorespiratory enzyme localised in leaf peroxisomes; from cucumber cotyledons Registry number: EC 1.1.1.- Synonym: ndh-reductase (26 Jun 1999) |
| NADH-Fe(III)EDTA oxidoreductase | <enzyme> From cryptococcus albidus; catalyses the formation of nad+ and fe(ii)edta from NADH and fe(iii)edta; forms ethylene from 2-oxo-4-methylthiobutyric acid Registry number: EC 1.6.99.- (26 Jun 1999) |
| NADH-hydroxylamine reductase | <enzyme> An enzyme catalyzing the reaction of hydroxylamine and NADH to form ammonia, NAD+, and water; used in a number of clinical assays. (05 Mar 2000) |
| NADH-hypothiocyanite oxidoreductase | <enzyme> Catalyses reduction of hypothiocyanite to thiocyanate; isolated from streptococcus sanguis Registry number: EC 1.6.99.- Synonym: nhor enzyme (26 Jun 1999) |
| NADH-methyl viologen reductase | <enzyme> Fad-protein from rhodospirillum rubrum which also reduces methylene blue and 2,6-dichlorophenol-indophenol Registry number: EC 1.6.- (26 Jun 1999) |
| NADH-vandate oxidoreductase | <enzyme> Catalyses conversion of vanadate to vanadyl in the presence of NADH but not NADPH Registry number: EC 1.16.- Synonym: NADH-v oxidoreductase (26 Jun 1999) |
| NADH2 oxidase | <enzyme> Chemical name: reduced nicotinamide adenine dinucleotide oxidase Registry number: EC 1.6.- Synonym: NADH oxidase (26 Jun 1999) |
| Nadi reaction | Formation of indophenol blue by the action of an oxidizing enzyme present in certain cells and tissues when they are treated with a solution of alpha-naphthol and dimethylparaphenylenediamine; by this method, cells of the myelocyte series, which give a positive reaction, may be distinguished from those of the lymphocyte series, which give a negative reaction; endothelial leukocytes give a variable reaction, probably positive when they have phagocytised the debris of myeloid cells. Synonym: Nadi reaction. (05 Mar 2000) |
| nadide | 3-Carbamoyl-1-beta-d-ribofuranosylpyridinium hydroxide;a nicotinamide adenine dinucleotide compound used as an antagonist to alcohol and narcotics. (05 Mar 2000) |
| nadir | The lowest point, point of greatest adversity or despair. (18 Nov 1997) |
| nadolol | <chemical> 5(3-((1,1-dimethylethyl)amino)-2-hydroxypropoxy)-1,2,3,4-tetrahydro-2,3-naphthaenediol. A non-selective beta-adrenergic antagonist with a long half-life, used in cardiovascular disease to treat arrhythmias, angina pectoris, and hypertension. Nadolol is also used for migraine and for tremor. Pharmacological action: adrenergic beta-antagonists, anti-arrhythmia agents, antihypertensive agents, sympatholytics. Chemical name: 2,3-Naphthalenediol, 5-(3-((1,1-dimethylethyl)amino)-2-hydroxypropoxy)-1,2,3,4-tetrahydro- (12 Dec 1998) |
