| ATP synthase | <enzyme> An enzyme that catalyses the conversion of phosphate and ADP into ATP during oxidativephosphorylation in mitochondriaand bacteria or photophosphorylationin chloroplasts. (09 Oct 1997) |
|---|---|
| ATP-ubiquitin-dependent proteinase | <enzyme> A component of the cytosolic ubiquitin-dependent proteolysis system Registry number: EC 3.4.- Synonym: ucden (26 Jun 1999) |
| caged ATP | <biochemistry> A derivative of ATP that is not biologically active until a photosensitive bond has been cleaved. (21 Mar 1998) |
| phosphoenolpyruvate carboxykinase (ATP) | <enzyme> An enzyme of the lyase class that catalyses the conversion of ATP and oxaloacetate to ADP, phosphoenolpyruvate, and carbon dioxide. The enzyme is found in some bacteria, yeast, and trypanosoma, and is important for the photosynthetic assimilation of carbon dioxide in some plants. Chemical name: ATP:oxaloacetate carboxy-lyase (transphosphorylating) Registry number: EC 4.1.1.49 (12 Dec 1998) |
| seryl-tRNA-ATP phosphotransferase | <enzyme> Produces phosphoseryl trna; plays suppressor role in in vitro globin synthesis Registry number: EC 2.7.1.- Synonym: ser-trna ptase, seryl trna kinase (26 Jun 1999) |
| hydrogen-transporting ATP synthase | <enzyme> A group of enzymes which are involved in the reversible synthesis of ATP and that transport protons from the cytoplasmic to the matrix side of the mitochondrial membrane. The flow of protons through the f(0) channel results in ATP synthesis by f1. Chemical name: ATP phosphohydrolase (H+-transporting) Registry number: EC 3.6.1.34 (12 Dec 1998) |
| DNA topoisomerase (ATP-hydrolysing) | <enzyme> An ATP-requiring enzyme which, in the presence of magnesium ions, introduces negative supertwists into closed and possibly linear duplex DNA. The enzyme is implicated in DNA replication and transcription. It causes the storage of mechanical strain energy in the superhelical turns of DNA at the expense of ATP hydrolysis. Chemical name: DNA topoisomerase (ATP-hydrolysing) Registry number: EC 5.99.1.3 (12 Dec 1998) |
| oligophosphoglyceroyl-ATP 3'-phosphodiesterase | <enzyme> Located in mitochondrial fraction of rat liver; selectively hydrolyzes the oligo cpd to monomeric units of 3-phosphoglyceroyl-gamma-triphospho-5'-adenosine Registry number: EC 3.1.4.- Synonym: opg-ATP-phosphodiesterase (26 Jun 1999) |
| acid-citrate-dextrose | A citrate anticoagulant used for the collection and preservation of whole blood. It has largely been replaced by newer coagulants (CPD, Adsol) that allow for longer shelf life for blood and blood products. Acronym: ACD (05 Mar 2000) |
| bismuth ammonium citrate | Ammoniocitrate of bismuth; an intestinal astringent. (05 Mar 2000) |
| bismuth citrate | Used in the making of bismuth and ammonium citrate. (05 Mar 2000) |
| caffeine citrate | Citrated caffeine, a mixture of equal parts of caffeine and citric acid. (05 Mar 2000) |
| calcium citrate | <chemical> A colourless crystalline or white powdery organic, tricarboxylic acid occurring in plants, especially citrus fruits, and used as a flavoring agent, as an antioxidant in foods, and as a sequestrating agent. Pharmacological action: antioxidants. (12 Dec 1998) |
| carbetapentane citrate | 2-(Diethylaminoethoxy)ethyl 1-phenylcyclopentyl-1-carboxylate citrate;it has atropine-like and local anaesthetic actions and effectively suppresses acute cough due to common upper respiratory infections. (05 Mar 2000) |
| gallium-67 citrate | <radiology> Analogue of ferric iron, decay: by electron capture to ground state of Zn-67, energy levels: 92 KeV (40%); 184 KeV (23%); 296 KeV (21%), physiological half life: 3.3 days (78 hr), biological half life: 2-3 weeks, binding sites: serum: transferrin, haptoglobin, albumin, globulins, tissue: lactoferrin, PMN's (viable and nonviable), lymphocytes, macrophages, bacteria and fungi, tumour cell-associated transferrin receptor see: gallium: indications (12 Dec 1998) |
