| thymicolymphatic | Relating to the thymus and the lymphatic system. (05 Mar 2000) |
|---|---|
| thymidine | <biochemistry> Term that is always used in practice for the nucleoside thymine deoxyriboside, not the riboside which naming of the other nucleosides might lead one to expect. (18 Nov 1997) |
| thymidine 5'-diphosphate | Thymidine esterified at its 5' position with diphosphoric acid. Acronym: dTDP (05 Mar 2000) |
| thymidine 5'-monophosphate | A major constituent of DNA. Synonym: thymidine 5'-monophosphate, thymine nucleotide. (05 Mar 2000) |
| thymidine 5'-triphosphate | Thymidine esterified at its 5' position with triphosphoric acid; the immediate precursor of thymidylic acid in DNA. Acronym: dTTP (05 Mar 2000) |
| thymidine kinase | <enzyme> Of pyrimidine salvage, catalysing phosphorylation of thymine deoxyriboside to form its 5' phosphate, the nucleotide thymidylate. Animal cells lacking this enzyme can be selected by lethal synthesis, for example by resistance to bromodeoxyuridine and can be used as parentals in somatic hybridisation, since they are unable to grow in HAT medium. (18 Nov 1997) |
| thymidine monophosphate | <chemical> 5-thymidylic acid. A thymine nucleotide containing one phosphate group esterified to the deoxyribose moiety. Chemical name: 5'-Thymidylic acid (12 Dec 1998) |
| thymidine permease | <chemical> (26 Jun 1999) |
| thymidine phosphorylase | <enzyme> The enzyme catalyzing the transfer of 2-deoxy-d-ribose from thymidine to orthophosphate, thereby liberating thymidine. Chemical name: Thymidine:orthophosphate deoxy-D-ribosyltransferase Registry number: EC 2.4.2.4 (12 Dec 1998) |
| thymidine triphosphate | A molecule which consists of the nitrogenous base thymine linked to the sugar ribose and which has a chain of three phosphate groups attached to the ribose in a linear fashion. TTP is required for DNA and RNA synthesis since it is a direct precursor molecule. (09 Oct 1997) |
| thymidine-diphospho-4-keto-6-deoxyglucose epimerase | <enzyme> Isolated from saccharopolyspora erythraea; catalyses the formation of tdp-4-keto-l-rhamnose from thymidine-diphospho-4-keto-6-deoxy-d-glucose Registry number: EC 5.1.3.- Synonym: tdkd-glucose epimerase, tdp-4-keto-6-deoxyglucose 3,5-epimerase, kde gene product (26 Jun 1999) |
| thymidylate synthase | <enzyme> An enzyme of the transferase class that catalyses the reaction 5,10-methylenetetrahydrofolate and dump to dihydrofolate and dtmp in the synthesis of thymidine triphosphate. Chemical name: 5,10-Methylenetetrahydrofolate:dUMP C-methyltransferase Registry number: EC 2.1.1.45 (12 Dec 1998) |
| thymidylate synthase-dihydrofolate reductase | <chemical> Bifunctional multienzyme complex purified from leishmania major Synonym: ts-dhfr, dhfr-ts (26 Jun 1999) |
| thymidylic acid | A major constituent of DNA. Synonym: thymidine 5'-monophosphate, thymine nucleotide. (05 Mar 2000) |
| thymin | See: thymopoietin. (05 Mar 2000) |
