| urate oxidase | <enzyme> An enzyme that catalyses the conversion of urate and unidentified products. It is a copper protein. The initial products decompose to form allantoin. Chemical name: Urate:oxygen oxidoreductase Registry number: EC 1.7.3.3 (12 Dec 1998) |

| urate | <physiology> A salt of uric acid; as, sodium urate; ammonium urate. Origin: Cf. F. Urate. Source: Websters Dictionary (01 Mar 1998) |
|---|---|
| urate crystals stain | <technique> A stain using silver methenamine to detect crystals, which polarise light in contrast with calcium crystals; useful in diagnosing gout and kidney infarcts resulting from uric acid build-up. (05 Mar 2000) |
| acetaldehyde oxidase | <enzyme> Acetaldehyde is converted to acetate Registry number: EC 1.2.- (26 Jun 1999) |
| acyl-CoA oxidase | <enzyme> Catalyses stoichiometric conversion of palmitoyl-CoA and o2 into 2-hexadecenoyl-CoA and h2o2; oxidises acyl-CoA's with carbon chain lengths of 4 to 20; most active toward lauroyl-CoA, but not acetyl- or succinyl-CoA Registry number: EC 1.3.3.6 Synonym: fatty acyl CoA oxidase, fatty acyl-coenzyme a oxidase, fatty acid acyl-CoA oxidase, acox, pox1 gene product (26 Jun 1999) |
| adrenaline oxidase | amine oxidase (flavin-containing) |
| aldehyde oxidase | <enzyme> Broad substrate specificity Registry number: EC 1.2.3.1 Synonym: n1-methylnicotinamide oxidase I, n-nitrosoreductase (26 Jun 1999) |
| alternative oxidase | <enzyme> The terminal oxidase in alternative pathway respiration, as seen in plants like sauromatum guttatum (voodoo lily); amino acid sequence for tobacco alternative oxidase (aox1) in first source Registry number: EC 1.- Synonym: aox1 gene product, aox2 gene product, aox3 gene product (26 Jun 1999) |
| alternative oxidase pathway | Pathway of mitochondrial electron transport in higher plants, particularly in fruits and seeds, that does not involve cytochrome oxidase and thus is resistant to cyanide. (18 Nov 1997) |
| amine oxidase | <enzyme> A group of enzymes including those oxidizing primary monoamines, diamines, and histamine. They are copper proteins, and, as their action depends on a carbonyl group, they are sensitive to inhibition by saemicarbazide. Chemical name: Amine:oxygen oxidoreductase (deaminating)(copper-containing) Registry number: EC 1.4.3.6 (12 Dec 1998) |
| amine oxidase (copper-containing) | An oxidoreductase containing copper, and perhaps pyridoxal phosphate, and carrying out the same reaction as amine oxidase (flavin-containing). Synonym: amine oxidase (pyridoxal-containing), diamine oxidase, diamino oxyhydrase, histaminase. (05 Mar 2000) |
| amine oxidase (flavin-containing) | An oxidoreductase containing flavin and oxidizing amines with the aid of O2 and water to aldehydes or ketones with the release of NH3 and H2O2. Acted upon by antidepressants. Synonym: adrenaline oxidase, diamine oxidase, monoamine oxidase, tyraminase, tyramine oxidase. (05 Mar 2000) |
| amine oxidase (pyridoxal-containing) | amine oxidase (copper-containing) |
| arginine oxidase | <enzyme> Catalyses the oxidative deamination from arginine to 2-ketoarginine Registry number: EC 1.4.3.- Synonym: arginine dehydrogenase (26 Jun 1999) |
| arsenite oxidase | <enzyme> Two n-terminal amino acid iron-sulfur protein containing molybdenum; detoxifies arsenite to arsenate Registry number: EC 1.16.- (26 Jun 1999) |
| aryl-alcohol oxidase | <enzyme> Flavoprotein acting on a variety of benzyl, cinnamyl, naphthyl and aliphatic unsaturated alcohols Registry number: EC 1.1.3.7 (26 Jun 1999) |
