| p-aminohippuric acid synthase | <enzyme> An enzyme in the liver that catalyses the synthesis of p-aminohippuric acid from p-aminobenzoic acid (or the CoA-derivative) and glycine. It may be identical with glycine acyltransferase. Acronym: PAH (05 Mar 2000) |
|---|---|
| cobyric acid synthase | <enzyme> From pseudomonas denitrificans; amidates four carboxylate groups of cobyrinic acid Registry number: EC 2.6.1.- Synonym: cobq gene product (26 Jun 1999) |
| cobyrinic acid a,c-diamide synthase | <enzyme> Encoded by cobb gene; from pseudomonas denitrificans Registry number: EC 2.6.1.- Synonym: co ac-a,c-d synthase (26 Jun 1999) |
| poly(3-hydroxyalkanoic acid) synthase | <enzyme> Synthesises polyhydroxyalkanoates consisting of medium-chain-length 3-hydroxyalkanoic acids, including poly(3-hydroxybutyrate) Registry number: EC 2.3.1.- Synonym: pha synthase, polyhydroxyalkanoate synthase (26 Jun 1999) |

| hydrogenobyrinic acid synthase | <enzyme> Pseudomonas denitrificans enzyme which is proposed to transfer a methyl group from c-11 to c-12 of precorrin-8x Registry number: EC 5.4.99.- Synonym: cobh gene product (26 Jun 1999) |
| d-aminolevulinic acid synthase | <enzyme> An enzyme that catalyses the reaction of succinyl-CoA with glycine to form d-aminolevulinic acid, coenzyme A, and CO2. The committed step in porphyrin biosynthesis. Acronym: ALA (05 Mar 2000) |
| delta(1)-tetrahydrocannabinolic acid synthase | <enzyme> Catalyses the oxidocyclization of cannabigerolic acid without requiring molecular oxygen, coenzymes, or cofactors; n-terminal amino acid sequence given in first source Registry number: EC 5.3.- Synonym: delta(1)-thca synthase (26 Jun 1999) |
| o-succinylbenzoic acid synthase | <enzyme> E coli enzyme; with shchc synthase catalyses formation of o-succinylbenzoic acid from isochorismic acid and alpha-ketoglutarate in presence of thiamine pyropyrophosphate; succinic saemialdehyde anion is formed by decarboxylation of alpha-ketoglutarate by thiamine pyrophosphate; anion then attacks isochorismic acid, initiating aromatization with elimination of pyruvate and h2o Registry number: EC 4.1.99.- Synonym: ortho-succinylbenzoic acid synthase, osb synthase, 2-succinylbenzoic acid synthase (26 Jun 1999) |

| monounsaturated fatty acids | A fatty acid chain with at least two empty spaces that could be hydrogenated (have a hydrogen atom added). Saturated (hydrogenated) fatty acids are a greater health risk for the development of atherosclerotic vascular disease. (27 Sep 1997) |
| saturated fatty acids | In eukaryotic membranes refers to stearic, palmitic and myristic acids, that are linear aliphatic chains with no double bonds. Prokaryotes have numerous branched chain saturated fatty acids. (18 Nov 1997) |
| omega 3 fatty acids | A class of fatty acids that have a double bond three carbons from the methyl moiety; reportedly, they play a role in lowering cholesterol and LDL levels. Synonym: omega-3 fatty acids. (05 Mar 2000) |
| fatty | Containing fat, or having the qualities of fat; greasy; gross; as, a fatty substance. <medicine> Fatty acid, a tumour consisting of fatty or adipose tissue; lipoma. Source: Websters Dictionary (01 Mar 1998) |
