cholesterol test
| cholesterol oxidase | <enzyme> An enzyme that catalyses the oxidation of cholesterol in the presence of molecular oxygen to 4-cholesten-3-one and hydrogen peroxide. The enzyme is not specific for cholesterol, but will also oxidise other 3-hydroxysteroids. Chemical name: Cholesterol:oxygen oxidoreductase Registry number: EC 1.1.3.6 (12 Dec 1998) |
|---|---|
| methanol oxidase | <enzyme> Contains fad and flavin semiquinone; from the yeast hansenula polymorpha Registry number: EC 1.1.99.- (26 Jun 1999) |
| methyl sterol oxidase | <enzyme> Converts sterol 4-methyl to carboxylic acid; requires NADH or NADPH Registry number: EC 1.- Synonym: methyl sterol mixed function oxidase, 4-methyl sterol oxidase, methylsterol oxidase, 4alpha-methylsterol oxidase (26 Jun 1999) |
| phenol oxidase | <enzyme> An enzyme oxidizing benzenediols to semiquinones with O2. Synonym: monophenol monooxygenase, phenol oxidase, phenolase, polyphenol oxidase, urushiol oxidase. (05 Mar 2000) |
| phenylalanine oxidase | <enzyme> Forms phenylpyruvate in the presence of air; consider also phenylalanine dehydrogenase (nad) which requires nad Registry number: EC 1.4.3.- Synonym: phenylalanine desaminase, l-phenylalanine oxidase, phenylalanine dehydrogenase (26 Jun 1999) |
| phenylethylamine oxidase | <enzyme> Contains a quinone cofactor, possibly topa quinone; isolated from arthrobacter globiformis; genbank u03517 Registry number: EC 1.4.3.- (26 Jun 1999) |
| phenylpyruvate oxidase | <enzyme> Phenylpyruvate is converted to o-hydroxyphenyl-acetic acid Registry number: EC 1.- (26 Jun 1999) |
| phytanic acid alpha-oxidase | <enzyme> May be the genetic defect in refsum's disease Registry number: EC 1.14.99.- Synonym: phytanic acid alpha-hydroxylase (26 Jun 1999) |
| monoamine oxidase | <enzyme> Catalysing breakdown of several biogenic amines, such as serotonin, adrenaline, noradrenaline, dopamine. (18 Nov 1997) |
| monoamine oxidase inhibitor | <pharmacology> A drug that interferes with the action of monoamine oxidase, slowing the breakdown of certain neurotransmitters. Used in the treatment of depression. Monoamine oxidase inhibitors are a group of antidepressant drugs that prevent the activity of the enzyme monoamine oxidase in the central nervous system (brain) thus affecting mood. The use of these medications is often restricted due to their severe side effects and drug (and food) interactions. Examples include isocarboxazid, pargyline, selegiline, furazolidone and phenelzine. Acronym: MAOI (26 Mar 1998) |
| monoamine oxidase inhibitors | A chemically heterogeneous group of drugs that have in common the ability to block oxidative deamination of naturally occurring monoamines. Although mao inhibitors are probably as effective as tricyclic antidepressants in the treatment of major depression, the complex, sometimes severe, and often unpredictable interactions between mao inhibitors and many other drugs and food-derived amines make their medical use difficult and potentially hazardous. (12 Dec 1998) |
| monophenol oxidase | <enzyme> An enzyme of the oxidoreductase class that catalyses the reaction between l-tyrosine, l-dopa, and oxygen to yield l-dopa, dopaquinone, and water. It is a copper protein that acts also on catechols, catalyzing some of the same reactions as catechol oxidase. Chemical name: Monophenol,L-dopa:oxygen oxidoreductase Registry number: EC 1.14.18.1 (12 Dec 1998) |
| coniferyl-alcohol oxidase | <enzyme> Converts coniferyl alcohol to dehydrodiconiferyl alcohol and pinoresinol, intermediates in the formation of lignin in pine trees; requires o2 Registry number: EC 1.13.11.- (26 Jun 1999) |
| coproporphyrinogen oxidase | <enzyme> One of the enzymes active in haem biosynthesis. It catalyses the oxidative decarboxylation of coproporphyrinogen III to protoporphyrinogen III by the conversion of two propionic acid groups to two vinyl groups. It can act under both aerobic and anaerobic conditions. Chemical name: Coproporphyrinogen:oxygen oxidoreductase (decarboxylating) Registry number: EC 1.3.3.3 (12 Dec 1998) |
| polyamine oxidase | <enzyme> Aminoacetone is oxidatively deaminated to methylglyoxal; spermidine gives putrescine and 3-aminopropionaldehyde; spermine gives spermidine and 3-aminopropionaldehyde Registry number: EC 1.5.3.3 Synonym: spermine oxidase, spermidine oxidase, aminoacetone oxidase (26 Jun 1999) |
