amine | <biochemistry> An organic compound containing nitrogen, any member of a group of chemical compounds formed from ammonia by replacement of one or more of the hydrogen atoms by organic (hydrocarbon) radicals. The amines are distinguished as primary, secondary and tertiary, according to whether one, two or three hydrogen atoms are replaced. The amines include allylamine, amylamine, ethylamine, methylamine, phenylamine, propylamine and many other compounds. (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.

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) |
amine oxidoreductases | <enzyme> Enzymes catalyzing the dehydrogenation of secondary amines, introducing a c=n double bond as the primary reaction. In some cases this is later hydrolyzed. Registry number: EC 1.5. (12 Dec 1998) |
Amine Precursor Uptake and Decarboxylation | <pharmacology, physiology> Paracrine cells of which argentaffin cells are an example. Usage of the term APUD is neither helpful nor memorable. Acronym: APUD (11 Nov 1997) |
amine sulfotransferase | <enzyme> Catalyses reversibly the reaction of 3'-phosphoadenylylsulfate and an arylamine to yield adenosine 3',5'-bisphosphate and an arylsulfamate Registry number: EC 2.8.2.3 Synonym: aniline sulfotransferase, arylamine sulfotransferase (26 Jun 1999) |
amine tetrazolium reductase | <enzyme> Tetrazolium salts as hydrogen acceptors Registry number: EC 1.4.- Synonym: tryptamine dehydrogenase, monoamine tetrazolium reductase, monoamine dehydrogenase (26 Jun 1999) |
aminergic | Relating to nerve cells or fibres. (05 Mar 2000) |
amines | A group of compounds derived from ammonia by substituting organic radicals for the hydrogens. (12 Dec 1998) |
adrenergic amine | An agent that evokes responses similar to those produced by adrenergic nerve activity (e.g., epinephrine, ephedrine, isoproterenol). Synonym: adrenergic amine, adrenomimetic amine, sympathetic amine. (05 Mar 2000) |
---|---|
adrenomimetic amine | An agent that evokes responses similar to those produced by adrenergic nerve activity (e.g., epinephrine, ephedrine, isoproterenol). Synonym: adrenergic amine, adrenomimetic amine, sympathetic amine. (05 Mar 2000) |
aromatic amine acetyltransferase | <enzyme> Marker for colourectal cancer Registry number: EC 2.3.1.- (26 Jun 1999) |
aromatic amine dehydrogenase | <enzyme> Oxidatively deaminates aromatic amines to aldehydes; phenazine methosulfate acts as electron acceptor Registry number: EC 1.5.99.- (26 Jun 1999) |
biogenic amine | <biochemistry> Amines found in both animals and plants that are frequently involved in signalling. There are several groups: ethanolamine derivatives include choline, acetylcholine AMP, muscarine, catecholamines include adrenaline, noradrenaline & dopamine, polyamines include spermine, indolylalkylamines include tryptamine & serotonin, betaines include carnitine, polymethyline diamines include cadaverine & putrescine. (18 Nov 1997) |
biogenic amine neurotransmitters | Biogenic amines released by neurons as intercellular messengers. The biogenic amines norepinephrine, dopamine, histamine, and serotonin are neurotransmitters in both the central and peripheral nervous systems. (12 Dec 1998) |
vasoactive amine | A substance, such as histamine or serotonin, that contains amino groups and is pharmacologically characterised by its action on the blood vessels (altering vascular caliber or permeability). (05 Mar 2000) |
receptors, biogenic amine | Cell surface proteins that bind biogenic amines with high affinity and regulate intracellular signals which influence the behaviour of cells. Biogenic amine is a chemically imprecise term which, by convention, includes the catecholamines epinephrine, norepinephrine, and dopamine, the indoleamine serotonin, the imidazolamine histamine, and compounds closely related to each of these. (12 Dec 1998) |
retina-specific amine oxidase | <enzyme> Genbank d88213 Registry number: EC 1.4.- Synonym: rao enzyme, human (26 Jun 1999) |
