| uridine monophosphate | <chemical> 5'-uridylic acid. A uracil nucleotide containing one phosphate group esterified to the sugar moiety in the 2', 3' or 5' position. Chemical name: 5'-Uridylic acid (12 Dec 1998) |
| uridine monophosphate kinase | <enzyme> Catalyses the phosphorylation of ump to udp; an aspect of EC 2.7.4.4 Registry number: EC 2.7.4.- Synonym: ump kinase, uridine-5-monophosphate kinase, uridylate kinase (26 Jun 1999) |
| 5-methyldeoxycytidine monophosphate aminohydrolase | <enzyme> Forms thymidylate; does not act on dcmp Registry number: EC 3.5.4.- Synonym: 5mdcmp aminohydrolase (26 Jun 1999) |
| 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) |
| cyclic adenylic acid | 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) |
| cyclic albuminuria | A functional albuminuria sometimes observed intermittently in cycles of 12 to 36 hours' duration, chiefly in younger persons; the degree of albuminuria is usually slight. Synonym: recurrent albuminuria. (05 Mar 2000) |
| cyclic AMP | <molecular biology> 3'5' cyclic ester of AMP. The first second messenger hormone signalling system to be characterised. Generated from ATP by the action of adenyl cyclase that is coupled to hormone receptors by G-proteins (GTP-binding proteins). CAMP activates a specific (cAMP dependent) protein kinase and is inactivated by phosphodiesterase action giving 5'AMP. Also functions as an extracellular morphogen for some slime moulds. (18 Nov 1997) |
| cyclic AMP-dependent protein kinase | Enzymes which attach phosphate groups to the serine or tyrosine amino acids on proteins as a means of regulating the proteins' activity in metabolic reactions. (09 Oct 1997) |
