| methemoglobin reductase | <enzyme> An erythrocyte enzyme which catalyses the reduction of methemoglobin (ferrihemoglobin) to haemoglobin (ferrohemoglobin). Deficiency produces the inherited disease familial methemoglobinaemia. In the absence of methemoglobin, the enzyme can also reduce methylene blue. Registry number: EC 1.6.- (12 Dec 1998) |
|---|---|
| NADPH-cytochrome c2 reductase | <enzyme> An enzyme catalyzing the reduction of 2 ferricytochrome c2 to 2 ferrocytochrome c2 at the expense of NADPH. Synonym: cytochrome c2 reductase. (05 Mar 2000) |
| NADPH-ferrihemoprotein reductase | <enzyme> A flavoprotein that catalyses the reduction of haem-thiolate-dependent monooxygenases and is part of the microsomal hydroxylating system. Its physiological acceptor is probably cytochrome p-450. Chemical name: NADPH:ferrihemoprotein oxidoreductase Registry number: EC 1.6.2.4 (12 Dec 1998) |
| NADPH-tetrazolium reductase | <enzyme> Reported to possess activity identical with NADPH cytochrome c reductase EC 1.6.2.4 Registry number: EC 1.6.2.- Synonym: NADPH-neotetrazolium reductase, NADPH-nbt reductase (26 Jun 1999) |
| thioredoxin reductase (NADPH) | <enzyme> Nadph:oxidised thioredoxin oxidoreductase. Registry number: EC 1.6.4.5 (12 Dec 1998) |
| methemoglobin | Haemoglobin in a form incapable of carrying oxygen. (12 Dec 1998) |
| cyanide methemoglobin | A relatively nontoxic compound of cyanide with methemoglobin, which is formed when methylene blue is administered in cases of cyanide poisoning. Synonym: cyanide methemoglobin. (05 Mar 2000) |
| acyl-CoA dehydrogenase (NADPH+) | Enzyme catalyzing the reversible reduction of enoyl-CoA derivatives of chain length 4 to 16, with NADPH as the hydrogen donor, forming acyl-CoA and NADP+. Synonym: enoyl-CoA reductase. (05 Mar 2000) |
| 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) |
| NADPH | <abbreviation> Nicotinamide adenine dinucleotide phosphate (reduced form). (05 Mar 2000) |
| NADPH dehydrogenase | <enzyme> A flavoprotein that reversibly oxidises NADPH to NADP and a reduced acceptor. Chemical name: NADPH:(acceptor) oxidoreductase Registry number: EC 1.6.99.1 (12 Dec 1998) |
| NADPH dehydrogenase (quinone) | A flavoprotein similar to NADH dehydrogenase (quinone), but oxidizing NADPH. Synonym: DT-diaphorase, menadione reductase, phylloquinone reductase, quinone reductase. (05 Mar 2000) |
| NADPH diaphorase | <enzyme> A flavoprotein that reversibly oxidises NADPH to NADP and a reduced acceptor. Chemical name: NADPH:(acceptor) oxidoreductase Registry number: EC 1.6.99.1 (12 Dec 1998) |
| NADPH oxidase | <enzyme> A plasma membrane-associated enzyme complex that catalyses the univalent reduction of oxygen using NADPH as an electron donor. The superoxide anion formed acts as an oxidant in the phagocyte microbicidal system, proceeding through a series of electron transfer reactions that form the respiratory burst. Various genetic defects in the system result in chronic granulomatous disease (granulomatous disease, chronic). Registry number: EC 1.6.- (12 Dec 1998) |
| NADPH - phenanthrenequinone oxidoreductase | <enzyme> Cytosolic enzyme from channel catfish; involved in futile redox cycling forming h2o2 leading to oxidative stress Registry number: EC 1.6.99.- Synonym: NADPH pq oxidoreductase (26 Jun 1999) |
| NADPH methemoglobin reductase |
an enzyme of the erythrocytes that catalyzes the reduction of methemoglobin to hemoglobin via oxidation of NADH. The physiological significance of the enzyme is uncertain; no endogenous intermediate electron carrier has been found, although the enzyme can be activated if methylene blue or other artificial electron acceptor is introduced. Called also methemoglobin reductase (NADPH).
