| 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) |
| octyl | <chemistry> A hypothetical hydrocarbon radical regarded as an essential residue of octane, and as entering into its derivatives; as, octyl alcohol. Origin: Octane + -yl. Source: Websters Dictionary (01 Mar 1998) |
| octyl gallate | Octyl 3,4,5-trihydroxybenzoate;an antioxidant. (05 Mar 2000) |

| 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) |
