|---|---|
| S-adenosyl-L-methionine-macrocin O-methyltransferase | <enzyme> Requires mg(ii) and s-adenosyl-l-methionine; specifically converts macrocin to tylosin by o-methylation at 3'''-position of macrocin Registry number: EC 2.1.1.- Synonym: macrocin o-methyltransferase, macrocin o-mt (26 Jun 1999) |
| S-adenosyl-L-methionine-norcoclaurine 6-O-methyltransferase | <enzyme> Catalyses the transfer of the s-methyl group of s-adenosyl-l-methionine to the 6-hydroxy group of norcoclaurine to produce coclaurine toward the synthesis of berberine in coptis japonica Registry number: EC 2.1.1.- Synonym: norcoclaurine 6-o-methyltransferase (26 Jun 1999) |
| S-adenosyl-L-methionine - scoulerine-9-O-methyltransferase | <enzyme> Catalyses the transfer of the s-methyl group of s-adenosyl-l-methionine to the 9-hydroxyl group of scoulerine during the biosynthesis of berberine; from cultured cells of coptis japonica; genbank d29809 Registry number: EC 2.1.1.- Synonym: adenosyl-met-smt, scoulerine 9-o-methyltransferase (26 Jun 1999) |
| S-adenosyl methionine thioether S-methyltransferase | <enzyme> 30,000 da enzyme methylates selenium in dimethylselenide, tellurium in dimethyltelluride, sulfur in dimethylsulfide and other thio ethers. Registry number: EC 2.1.1.- Synonym: dimethyl selenide methyltransferase, thioether methyltransferase (26 Jun 1999) |
| enkephalin, methionine | <chemical> Endogenous pentapeptide with morphine-like activity. The amino acid in position 5 is methionine. Chemical name: Adrenorphin (human), 6-de-L-arginine-7-de-L-arginine-8-de-L-valinamide- (12 Dec 1998) |
| L-methionine gamma-lyase | <enzyme> Pharmacological action: antimetabolites, antineoplastic Registry number: EC 4.4.1.11 Synonym: l-methionine alpha-deamino gamma-mercaptomethane-lyase, methionine dethiomethylase, l-methioninase, methioninase (26 Jun 1999) |
| active | Characterised by action, not passive, not expectant. (18 Nov 1997) |
| active acetate | <enzyme> Condensation product of coenzyme A and acetic acid, symbolised as CoAS~COCH3; intermediate in transfer of two-carbon fragment, notably in its entrance into the tricarboxylic acid cycle and in fatty acid synthesis. This coenzyme plays a huge role in intermediary metabolism, in which cells synthesise, break down or use nutrient molecules for energy production, growth, etc. Acetyl-coenzyme A synthase is found in bacteria and plants and catalyses the reaction in which acetate enters metabolic pathways and forms acetyl-coenzyme A. Synonym: acetyl-coenzyme A, active acetate. (05 Mar 2000) |
| active aldehyde | Any aldehyde derivative of thiamin pyrophosphate. (05 Mar 2000) |
| active anaphylaxis | Reaction following inoculation of antigen in a subject previously sensitised to the specific antigen, in contrast to passive anaphylaxis. (05 Mar 2000) |
| active biomass | <cell biology> The amount of a given culture that is actively growing. (06 May 1997) |
| active carbon dioxide | Activated carbon dioxide, a complex of N-carboxybiotin (biotin + CO2) and an enzyme; the form in which carbon dioxide is added to other molecules in carboxylations; e.g., to methylcrotonyl-CoA to form beta-methylglutaconyl in the catabolism of leucine, and to acetyl-CoA to form malonyl-CoA. See: acetyl-CoA carboxylase. (05 Mar 2000) |
| active caries | Microbial-induced lesions of teeth that are increasing in size. (05 Mar 2000) |
| active centre | The part of a macromolecule at which a substrate or ligand, upon binding, produces biological activity; for an enzyme, this is the catalytic centre, the site on an enzyme that catalyses the reaction. (05 Mar 2000) |
