| aryl hydrocarbon hydroxylases | <enzyme> A group of cytochrome p-450 (haem-thiolate) proteins which utilise reduced flavin or flavoprotein as one donor and incorporate one atom of oxygen. They act on many aromatic compounds. They are a component part of the mixed-function oxidase system and are important for the oxidation of many drugs and toxins such as phenobarbital, carcinogens, and insecticide. These enzymes are considered to be an aspect of EC 1.14.14.1. Registry number: EC 1.14.14.- (12 Dec 1998) |
| aryl sulphatase | <enzyme> Aryl sulphatases A, B and C comprise a group of enzymes originally assayed by their ability to hydrolyze O sulphate esters of aromatic substrates. Aryl sulphatase A, substrate cerebroside 3 sulphate, is deficient in metachromatic leukodystrophy. Aryl sulphatase B, substrate acetylhexosamine 4 sulphate in glycosaminoglycans, is deficient in Maroteaux-Lamy syndrome. Aryl sulphatase C hydrolyses oestrogen sulphates. All three are deficient in multiple sulphatase deficiency. (18 Nov 1997) |

| arylamidase | An amidohydrolase cleaving the acyl group from an anilide by hydrolysis, producing aniline and an acid anion. Synonym: arylamidase. (05 Mar 2000) |
| arylamine n-acetyltransferase | <enzyme> An enzyme that catalyses the transfer of acetyl groups from acetyl-CoA to arylamines. They have wide specificity for aromatic amines, particularly serotonin, and can also catalyze acetyl transfer between arylamines without CoA. Chemical name: Acetyl-CoA:arylamine N-acetyltransferase Registry number: EC 2.3.1.5 (12 Dec 1998) |
| arylamine N-hydroxylase | <enzyme> Cytochrome p-448 dependent Registry number: EC 1.14.13.- Synonym: 2-aminofluorene n-hydroxylase (26 Jun 1999) |

| alkyl and aryl transferases | <enzyme> A somewhat heterogeneous class of enzymes that catalyze the transfer of alkyl or related groups (excluding methyl groups). Registry number: EC 2.5 (12 Dec 1998) |
|---|---|
| receptors, aryl hydrocarbon | Cytoplasmic proteins that bind certain aryl hydrocarbons, translocate to the nucleus, and activate transcription of particular DNA segments. Ah receptors are identified by their high-affinity binding to several carcinogenic or teratogenic environmental chemicals including polycyclic aromatic hydrocarbons found in cigarette smoke and smog, heterocyclic amines found in cooked foods, and halogenated hydrocarbons including dioxins and polychlorinated biphenyls. No endogenous ligand has been identified, but an unknown natural messenger with a role in cell differentiation and development is suspected. (12 Dec 1998) |
