J acid
| hypoxanthine oxidase | <enzyme> Dehydrogenases involved in conversion of hypoxanthine to xanthine and xanthine to uric acid, as the final catabolism of purines. Deficient in the human disease xanthinuria. (18 Nov 1997) |
|---|---|
| N-acetyl-6-hydroxytryptophan oxidase | <enzyme> Phenol oxidase from aspergillus nidulans Registry number: EC 1.14.18.- (26 Jun 1999) |
| N-acetylhexosamine oxidase | <enzyme> Catlyzes the conversion of n-acetyl-d-glucosamine to n-acetylglucosaminic acid and peroxide Registry number: EC 1.1.3.- (26 Jun 1999) |
| NADH2 oxidase | <enzyme> Chemical name: reduced nicotinamide adenine dinucleotide oxidase Registry number: EC 1.6.- Synonym: NADH oxidase (26 Jun 1999) |
| NAD(P)H-adrenaline oxidase | <enzyme> Forms adrenochrome Registry number: EC 1.6.- (26 Jun 1999) |
| 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) |
| steroid alpha-ketol oxidase | <enzyme> In conjunction with corticosteroid side-chain-isomerase (EC 5.3.1.21) converts desoxycorticosterone to a 20-oxo-21-oic acid (pregnenoic acid) Registry number: EC 1.2.1.- (26 Jun 1999) |
| stobadine N-oxidase | <enzyme> Forms stobadine n-oxide Registry number: EC 1.7.- (26 Jun 1999) |
| nicotine oxidase | <enzyme> Cytochrome p-450 enzyme Registry number: EC 1.5.3.- (26 Jun 1999) |
| nifedipine oxidase | <enzyme> Cytochrome p-450 isozyme induced by pregnenolone 16alpha-carbonitrile Registry number: EC 1.14.99.- Synonym: cytochrome p-450(pcn1), cytochrome p-450 hpcn3, cytochrome p450p, cytochrome IIIa1, cytochrome p-450 (pcna), cytochrome p-450 3a4, cyt p450 3a4, cytochrome p450 3a1, cyp3a1, cyp3a4, p450 3a4, cytochrome p-450(pcn) (26 Jun 1999) |
| nitroalkane oxidase | <enzyme> Catalyses the conversion of oxygen and nitroalkane to hydrogen peroxide, aldehyde, and nitrite Registry number: EC 1.7.3.- (26 Jun 1999) |
| nopaline oxidase | <enzyme> Catalyses oxidative cleavage of nopaline into l-arginine and 2-ketoglutarate; no required cofactors; activity requires noxa and noxb gene products; isolated from agrobacterium tumefaciens Registry number: EC 1.5.99.- (26 Jun 1999) |
| succinate oxidase | <enzyme> Not the same as succinate dehydrogenase; involved in electron transport with succinate as substrate Registry number: EC 1.- Synonym: succinoxidase (26 Jun 1999) |
| sulfhydryl oxidase | <enzyme> 2rsh plus 02 gives rssr plus hydrogen peroxide; substrate sulfhydryl compounds may be replaced by glutathione or other specific as appropriate Registry number: EC 1.8.3.- Synonym: sulphydryl oxidase, s-s cross-linking enzyme, sulphydryloxidase (26 Jun 1999) |
| sulfide oxidase | <enzyme> Catalyses the conversion of hydrogen sulfide to sulfur; isolated from hyphomicrobium neptunium Registry number: EC 1.8.- (26 Jun 1999) |
