| hydroxyproline oxidase | <enzyme> Oxidises 4-hydroxy-l-proline to delta'-pyrroline-3-hydroxy-5-carboxylate Registry number: EC 1.5.99.- (26 Jun 1999) |
|---|
| 4-hydroxyproline oxidase | A flavoenzyme that catalyses the conversion of 4-hydroxyproline to d'-pyrroline-3-hydroxy-5-carboxylate using FAD; this enzyme appears to be deficient in individuals with hyperhydroxyprolinaemia, an enzyme that catalyses the reaction of 4-hydroxyproline with NAD+ to form NADH and 4-oxoproline. Synonym: 4-oxoproline reductase. (05 Mar 2000) |

| arabinosyl-hydroxyproline transferase | <enzyme> Involved in glycoprotein synthesis in plants Registry number: EC 2.4.2.- Synonym: ar-hpt, protein-arabinosyltransferase (26 Jun 1999) |
| hydroxyproline | Specific proline residues on the amino side of a glycine residue in collagen become hydroxylated at C4, before the polypeptides become helical, by the activity of prolyl hydroxylase. This enzyme has a ferrous ion at the active site and a reducing agent such as ascorbate is necessary to maintain the iron in the ferrous state. The presence of hydroxyproline is essential to produce stable triple helical tropocollagen, hence the problems caused by ascorbate deficiency in scurvy. This unusual amino acid is also present in considerable amounts in the major glycoprotein of primary plant cell walls (see HRGP). (18 Nov 1997) |
| hydroxyproline rich glycoprotein | See: HRGP. (18 Nov 1997) |
| 3-hydroxyproline | A derivative of proline found in certain collagens, particularly basement membrane collagen. Synonym: 3-hydroxy-2-pyrrolidinecarboxylic acid. (05 Mar 2000) |
| 4-hydroxyproline | 4-Hydroxy-2-pyrrolidinecarboxylic acid;the trans-l-isomer is an imino acid found among the hydrolysis products of collagen; not found in proteins other than those of connective tissue. A vitamin C deficiency will result in impaired formation of hydroxyproline. (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) |
| hydroxyproline oxidase |
an enzyme of the oxidoreductase class that catalyzes the oxidation of 4-hydroxyproline to form the 3-hydroxy analog of Δ1-pyrroline 5-carboxylate as part of the pathway of degradation of free hydroxyproline. Deficiency of the enzyme, an autosomal recessive trait, results in hydroxyprolinemia.
