| anthranilate monooxygenase | <enzyme> Catalyses the hydroxylation of anthranilate to hydroxyanthranilate in the presence of tetrahydropteridine and molecular oxygen; anthranilate hydroxylase is a synonym for this and EC 1.14.12.1 and EC 1.14.13.35 (formerly EC 1.14.12.2) Registry number: EC 1.14.16.3 Synonym: anthranilate 3-hydroxylase, anthranilate 3-monooxygenase (26 Jun 1999) |
| anthranilate phosphoribosyltransferase | <enzyme> An enzyme that catalyses the formation of n-5'-phosphoribosylanthranilic acid from anthranilate and phosphoribosylpyrophosphate, the first step in tryptophan synthesis in e. Coli. It exists in a complex with anthranilate synthase in bacteria. Chemical name: N-(5-Phospho-D-ribosyl)-anthranilate:pyrophosphate phospho-alpha-D-ribosyltransferase Registry number: EC 2.4.2.18 (12 Dec 1998) |
| anthranilate synthase | <enzyme> An enzyme that catalyses the formation of anthranilate (o-aminobenzoate) and pyruvic acid from chorismate and glutamine. Anthranilate is the biosynthetic precurser of tryptophan and numerous secondary metabolites, including inducible plant defense compounds. Chemical name: Chorismate pyruvate-lyase (amino-accepting) Registry number: EC 4.1.3.27 (12 Dec 1998) |
| benzoyl-CoA-anthranilate N-benzoyltransferase | <enzyme> Specific for anthranilate; almost no activity towards 4-hydroxyanthranilate; involved in phytoalexin biosyntesis Registry number: EC 2.3.1.- Synonym: b-CoA-anb transferase, benzoyl-coenzyme a-anthranilate n-benzoyltransferase (26 Jun 1999) |
| abstracting and indexing | Shortening or summarizing of documents; assigning of descriptors for referencing documents. (12 Dec 1998) |
| academies and institutes | Organizations representing specialised fields which are accepted as authoritative; may be non-governmental, university or an independent research organization, e.g., national academy of sciences, brookings institution, etc. (12 Dec 1998) |

| algae and fungi | Algae represent a group of spore-propagating plants, unicellular or undifferentiated into root, stem, and leaf. They include seaweed and many unicellular fresh water plants, most of which contain chlorophyll. They account for about 90% of the earth's photosynthetic activity. Fungi are eukaryotic, heterotrophic organisms that live as saprobes or parasites and include mushrooms, yeasts, smuts, molds, etc. They lack chlorophyll. (12 Dec 1998) |
| 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) |
| allergy and immunology | A medical specialty concerned with the hypersensitivity of the individual to foreign substances and protection from the resultant infection or disorder. (12 Dec 1998) |
| alligators and crocodiles | Large, long-tailed reptiles, including caimans, of the order loricata. (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) |
