| nucleotide pair | <molecular biology> Two nitrogenous bases (adenine and thymine or guanine and cytosine) held together by weak bonds. Two strands of DNA are held together in the shape of a double helix by the bonds between base pairs. (09 Oct 1997) |
|---|---|
| nucleotide phosphotransferase | <enzyme> Transfers phosphoric acid from an organic phosphate donor to the 2' or 3' hydroxyls of nucleosides and nucleotides Registry number: EC 2.7.1.- (26 Jun 1999) |
| nucleotide pyrophosphate transferase | <enzyme> Transfers the beta, gamma pyrophosphate group from ATP to 3'-hydroxy group of ribonucleotides, oligonucleotides or trna Registry number: EC 2.7.6.- (26 Jun 1999) |
| diphosphopyridine nucleotide | nAD |
| thymine nucleotide | A major constituent of DNA. Synonym: thymidine 5'-monophosphate, thymine nucleotide. (05 Mar 2000) |
| triphosphopyridine nucleotide | Former name for nicotinamide adenine dinucleotide phosphate. (05 Mar 2000) |
| flavin nucleotide | <biochemistry> Flavin derivatives that act as prosthetic groups (covalently linked cofactors) for flavin enzymes. (18 Nov 1997) |
| adenosine 3',5'-cyclic monophosphate | An activator of phosphorylase kinase and an effector of other enzymes, formed in muscle from ATP by adenylate cyclase and broken down to 5'-AMP by a phosphodiesterase; sometimes referred to as the "second messenger." A related compound (2',3') is also known. Synonym: cyclic adenylic acid, cyclic AMP, cyclic phosphate. Acronym: cAMP (05 Mar 2000) |
| adenosine 3',5'-cyclic phosphate phosphodiesterase | <enzyme> An enzyme that catalyses the hydrolysis of adenosine 3',5'-cyclic phosphate forming 5'-AMP. A crucial step in the regulation of cellular adenosine 3',5'-cyclic phosphate levels. Inhibited by caffeine. Synonym: cAMP phosphodiesterase. (05 Mar 2000) |
| adenosine cyclic phosphate | An activator of phosphorylase kinase and an effector of other enzymes, formed in muscle from ATP by adenylate cyclase and broken down to 5'-AMP by a phosphodiesterase; sometimes referred to as the "second messenger." A related compound (2',3') is also known. Synonym: cyclic adenylic acid, cyclic AMP, cyclic phosphate. Acronym: cAMP (05 Mar 2000) |
| amino acids, cyclic | A class of amino acids characterised by a closed ring structure. (12 Dec 1998) |
| canine infectious cyclic thrombocytopenia | An infection of dogs with the rickettsia Ehrlichia platys characterised by recurrent cyclic thrombocytopenia. (05 Mar 2000) |
| receptors, cyclic AMP | Cell surface proteins that bind cyclic AMP with high affinity and trigger intracellular changes which influence the behaviour of cells. The best characterised cyclic AMP receptors are those of the slime mold dictyostelium discoideum. The transcription regulator cyclic AMP receptor protein of prokaryotes is not included nor are the eukaryotic cytoplasmic cyclic AMP receptor proteins which are the regulatory subunits of cyclic AMP-dependent protein kinases. (12 Dec 1998) |
| cyclic | <chemistry> Pertaining to or occurring in a cycle or cycles, the term is applied to chemical compounds that contain a ring of atoms in the nucleus. Origin: Gr. Kyklikos (18 Nov 1997) |
| cyclic 2,3-diphosphoglycerate synthetase | <enzyme> Catalyses the conversion of 2,3-diphosphoglycerate and ATP to cyclic 2,3-diphosphoglycerate and ADP and pi in the presence of mg+ Registry number: EC 4.6.1.- Synonym: cdpg synthetase (26 Jun 1999) |
