| dcmp deaminase | <enzyme> An enzyme that catalyses the hydrolytic deamination of deoxycytidylic acid to deoxyuridylic acid and ammonia. It plays an important role in the regulation of the pool of deoxynucleotides in higher organisms. The enzyme also acts on some 5-substituted deoxycytidylic acids. Chemical name: dCMP aminohydrolase Registry number: EC 3.5.4.12 (12 Dec 1998) |

| deaminase | <enzyme> An enzyme which removes amino groups from compounds, producing ammonia in the process. (09 Oct 1997) |
| threonine deaminase | <enzyme> A pyridoxal-phosphate protein that catalyses the deamination of threonine to 2-ketobutyrate and ammonia. The role of this enzyme can be biosynthetic or biodegradative. In the former role it supplies 2-ketobutyrate required for isoleucine biosynthesis, while in the latter it is only involved in the breakdown of threonine to supply energy. Chemical name: L-Threonine hydro-lyase (deaminating) Registry number: EC 4.2.1.16 (12 Dec 1998) |
| 2,5-diamino-6-ribitylamino-4(3H)-pyrimidinone 5'-phosphate deaminase | <enzyme> Forms 5-amino-6-ribitylamino-2,4-(1h,3h)-pyrimidinedione 5'-phosphate, intermediate in biosynthesis of riboflavin Registry number: EC 3.5.4.- Synonym: drap 5'-p deaminase (26 Jun 1999) |
| 3-aminobutyryl-CoA deaminase | <enzyme> Forms crotonyl CoA Registry number: EC 4.3.1.- Synonym: 3-aminobutyryl-coenzyme a deaminase (26 Jun 1999) |
| folic acid deaminase | <enzyme> Chemotaxis regulating enzyme; splits folic acid into 6-hydroxymethylpterin and p-aminobenzoylglutamic acid Registry number: EC 3.5.4.- Synonym: folic acid inactivating enzyme, folic acid c9-n10 cleaving enzyme (26 Jun 1999) |
| adenosine | <biochemistry> A ribonucleotide which consists of the nitrogenous base adenine linked to the sugar ribose. <drug> A cardiac drug used in terminating PSVT involving reentry pathways that include the AV node or Wolff-Parkinson-White syndrome. For atrial flutter, atrial fibrillation, atrial or ventricular tachycardias, adenosine may produce transient AV block that may help identify the rhythm. Pharmacologic action: Endogenous purine nucleoside that depresses AV node and sinus node activity. Brief duration of action (1-2 min). Dose: Rapid 6 mg IV bolus over 1-3 sec. May repeat at 12 mg IV bolus within 1-2 min Patients taking theophylline may require larger doses. Use a smaller dose with cardiac transplant patients. Potential complications: Common but transient - flushing, dyspnea, chest pain, bradycardia, and ventricular ectopy. Theophylline (and caffeine) blocks adenosine's effects. Dipyridamole potentiates adenosine's effects. Use other agents to avoid these drug interactions. (15 Mar 2000) |
| 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 3'-phosphate | 3'-Adenylic acid. See: adenylic acid. (05 Mar 2000) |
| adenosine 3'-phosphate 5'-phosphosulfate | 3'-phosphoadenosine 5'-phosphosulfate;an intermediate in the formation of urinary ethereal sulfates, notable for containing a "high energy" sulfate bond; the 3'-OH of adenosine is replaced by -OPO3H2, the 5'-OH by -OP(O2H)-OSO3H. Synonym: active sulfate. Acronym: PAPS (05 Mar 2000) |
| adenosine 5'-diphosphate | A condensation product of adenosine with pyrophosphoric acid, formed from ATP by the hydrolysis of the terminal phosphate group of the latter compound. Acronym: ADP (05 Mar 2000) |
| adenosine-5'-(n-ethylcarboxamide) | <chemical> A stable adenosine a1 and a2 receptor agonist. Experimentally, it inhibits camp and cgmp phosphodiesterase activity. Pharmacological action: antineoplastic agent, vasodilator agents. (12 Dec 1998) |
| adenosine 5'-phosphate | 5'-Adenylic acid. See: adenylic acid. (05 Mar 2000) |
| adenosine 5'-phosphoramidate hydrolase | <enzyme> Hydrolyzes nucleoside 5'-monophosphoramidates into nucleoside 5'-phosphates and ammonia Registry number: EC 3.9.1.- Synonym: ampn hydrolase, nucleoside monophosphoramidate hydrolase (26 Jun 1999) |
