| NAD(P)+-dependent cholesterol dehydrogenase | <enzyme> Oxidises the 3 beta-oh group of cholesterol to cholestenone in the presence of NADP+ Registry number: EC 1.1.1.- Synonym: NADP+-dc-dehydrogenase, cholesterol 3-dehydrogenase (26 Jun 1999) |

| NAD(p)-arginine ADP-ribosyltransferase | <enzyme> An enzyme that catalyses the transfer of the ADP-ribose moiety from NAD to specific protein substrates with agmatine, arginine-type compounds, or guanidine as acceptors. This reaction can be catalyzed by prokaryotic and eukaryotic enzyme systems. Mono-ADP-ribosylation is a mechanism of action common to several bacterial toxins. It effects profound changes in cellular metabolism, such as activation of adenylate cyclase, regulation of protein synthesis at the level of elongation factor 2, and ion transport across biological membranes. Chemical name: NAD(+)-L-arginine ADP-D-ribosyltransferase Registry number: EC 2.4.2.31 (12 Dec 1998) |
| NAD(P)-reducing nickel hydrogenase | <enzyme> From cyanobacterium, synechocystis; genbank x97610 Registry number: EC 1.12.1.- (26 Jun 1999) |
| NAD(p)h dehydrogenase (quinone) | <enzyme> A flavoprotein that reversibly catalyses the oxidation of NADH or NADPH by various quinones and oxidation-reduction dyes. Since the enzyme is a part of the mitochondrial respiratory chain, defects or deficiencies of this enzyme are an important cause of neurological diseases such as parkinsonism. It may have a protective effect against cancer caused by quinones or their metabolic precursors. The enzyme is inhibited by dicoumarol, capsaicin, and caffeine. Chemical name: NAD(P)H:(quinone-acceptor) oxidoreductase Registry number: EC 1.6.99.2 (12 Dec 1998) |
| NAD(P)H plastoquinone oxidoreductase | <enzyme> Specified by chloroplast gene Registry number: EC 1.6.99.- Synonym: NADPH pl oxidoreductase (26 Jun 1999) |
| NAD(P)H-adrenaline oxidase | <enzyme> Forms adrenochrome Registry number: EC 1.6.- (26 Jun 1999) |
| NAD+ | <abbreviation> Nicotinamide adenine dinucleotide (oxidised form). (05 Mar 2000) |
| NAD+ ADP-ribosyltransferase | <enzyme> An enzyme isolated from the nuclei of a variety of cells. It catalyses the incorporation of ADP-ribose groups of NAD+ into a homopolymer of repeating ADP-ribose units. Chemical name: NAD+:poly(adenosine diphosphate D-ribose)-acceptor ADP-D-ribosyltransferase Registry number: EC 2.4.2.30 (12 Dec 1998) |
| NAD+ nucleosidase | <enzyme> An enzyme that catalyses the hydrolysis of NAD to nicotinamide and adpribose. Chemical name: NAD+ glycohydrolase Registry number: EC 3.2.2.5 (12 Dec 1998) |
| NAD+ pyrophosphorylase | <enzyme> An enzyme that participates in the synthesis of NAD+; it reacts nicotinamide mononucleotide with ATP to produce NAD+ and pyrophosphate; it will also act on nicotinate mononucleotide. (05 Mar 2000) |
| NAD+ synthetase | <enzyme> An enzyme that catalyses the reaction of ATP, l-glutamine, and nicotinate adenine dinucleotide to form NAD+, ADP, and l-glutamate. (05 Mar 2000) |
| NADase | nAD+ nucleosidase |
| NADH | <abbreviation> Nicotinamide adenine dinucleotide (reduced form). (05 Mar 2000) |
| NADH dehydrogenase | <enzyme> A flavoprotein containing iron. Cytochrome c may act as receptor. The enzyme reversibly catalyses the oxidation of NADH to NAD and reduced acceptor. An inherited deficiency of this complex results in overwhelming acidosis. Synonym: cytochrome c reductase. Chemical name: NADH:(acceptor) oxidoreductase Registry number: EC 1.6.99.3 (12 Dec 1998) |
| NADH kinase | <enzyme> From saccharomyces cerevisiae; phosphorylate diphosphopyridine nucleotides; found exclusively in the mitochondria Registry number: EC 2.7.1.86 (26 Jun 1999) |
