| dehydrogenase | <enzyme> Enzyme that oxidizes a substrate by transferring hydrogen to an acceptor that is either NAD/NADP or a flavin enzyme. (18 Nov 1997) |
|---|---|
| delta-1-piperideine-6-carboxylate dehydrogenase | <enzyme> From streptomyces clavuligerus and other cephamycin c-producing actinomycetes; converts delta-1-piperideine-6-carboxylate to alpha-aminoadipic acid Registry number: EC 1.5.1.- Synonym: p6c dehydrogenase (26 Jun 1999) |
| delta(5)-3 beta-hydroxysteroid dehydrogenase | <enzyme> Converts dehydroepiandrosterone to delta-4-androstene-3,17-dione Registry number: EC 1.1.1.- Synonym: dbhdase, 3 beta-hydroxy-5-ene-steroid dehydrogenase, steroid-delta(5)-3-ol dehydrogenase (26 Jun 1999) |
| D-erythritol 1-phosphate dehydrogenase | <enzyme> Chemical name: d-erythro-tetritol 1-phosphate nad(+) 2-oxidoreductase Registry number: EC 1.1.1.- (26 Jun 1999) |
| desulfo xanthine dehydrogenase | <enzyme> Naturally occuring inactive form of xanthine dehydrogenase Registry number: EC 1.1.1.- (26 Jun 1999) |
| D-fructose 5-dehydrogenase | <enzyme> Catalyses the oxidation of fructose with any acceptor to 5-ketofructose and reduced acceptor Registry number: EC 1.1.99.11 (26 Jun 1999) |
| dihydroanisoin dehydrogenase | <enzyme> Catalyses the NADH-dependent reduction of the carbonyl group of benzoin and anisoin; oxidoreductases from pseudomonas fluorescens biovar i Registry number: EC 1.1.1.- (26 Jun 1999) |
| dihydrolipoamide dehydrogenase | <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) |
| dihydroorotate dehydrogenase | <enzyme> Converts (s)-dihydroorotate and an aceptor to orotate and a reducted aceptor; dihydro-orotate dehydrogenase was see dihydro-orotate oxidase 1977-93 Registry number: EC 1.3.99.11 Synonym: dihydro-orotate-cytochrome c reductase, dihydro-orotate dehydrogenase (26 Jun 1999) |
| dihydropyrimidine dehydrogenase | <enzyme> An enzyme in pyrimidine biosynthesis that reacts 5,6-dihydrouracil with NADP+ to form uracil and NADPH; it also acts on dihydrothymine; a deficiency of this enzyme can result in hyperuracil thyminuria. Synonym: dihydrouracil dehydrogenase. (05 Mar 2000) |
| dihydrouracil dehydrogenase | <enzyme> Uses nad Registry number: EC 1.3.1.1 Synonym: dihydrothymine dehydrogenase (26 Jun 1999) |
| dimethylamine dehydrogenase | <enzyme> From hyphomicrobium, 6-s-cysteinyl-fmn is coenzyme Registry number: EC 1.5.99.- (26 Jun 1999) |
