| trans-splicing | Formation of spliced products containing portions of two different transcripts. (05 Mar 2000) |
|---|---|
| transacetylase | Any enzyme transferring acetyl groups from one compound to another. See: acetyl-CoA acetyltransferase, choline acetyltransferase, dihydrolipoamide acetyltransferase. Synonym: transacetylase. (05 Mar 2000) |
| transacetylation | Transfer of an acetyl group (CH3CO-), from one compound to another; such reactions, usually involving formation of acetyl-CoA, occur notably in the initiation of the tricarboxylic acid cycle by the transfer of an acetyl group to oxaloacetate to form citrate. (05 Mar 2000) |
| transaction | 1. Interaction arising from the encounter of two or more persons. 2. In transactional analysis, the unit of analysis involving a social stimulus and a response. (05 Mar 2000) |
| transactional analysis | A psychoanalytic therapy wherein each social transaction is analyzed to determine the involved ego state (whether parent-like, child-like, or adult-like) as a basis for understanding behaviour. (12 Dec 1998) |
| transactional psychotherapy | Psychotherapy with central emphasis on the actual day-to-day interactions (transactions) between the patient and other people in his life. (05 Mar 2000) |
| transactivation | <molecular biology> Stimulation of transcription by a transcription factor binding to DNA and activating adjacent proteins. (17 Mar 1998) |
| transacylase | <enzyme> An enzyme that transfers an acyl group, for example transacetylase that transfers an acetyl group from acetyl lipoamide to coenzyme A. (18 Nov 1997) |
| transacylases | <enzyme> Enzymes of the transferase class that catalyze the transfer of an acyl group from a donor (often the corresponding acyl coenzyme a derivative) to an acceptor compound. Registry number: EC 2.3. (12 Dec 1998) |
| transacylation | The reversible transfer of acyl groups. (05 Mar 2000) |
| transaldolase | <enzyme> Together with transketolase, links the pentose phosphate pathway with glycolysis by converting pentoses to hexoses. (18 Nov 1997) |
| transaldolation | A reaction involving the transfer of an aldol group (CH2OH-CO-CHOH-) from one compound to another; such reactions generally involve the sugar phosphates and occur in the phosphogluconate oxidation pathway of carbohydrate catabolism. (05 Mar 2000) |
| transamidation | The transfer of NH2 from an amide moiety (e.g., from glutamine) to another molecule. (05 Mar 2000) |
| transamidinases | amidinotransferases |
| transamidination | A reaction involving the transfer of an amidine group (NH2C==NH) from one compound to another; the amidine donor is generally l-arginine and the reaction is of significance in the biosynthesis of creatine. (05 Mar 2000) |
