| ADH | Academy of Dentistry for the Handicapped; adhesion; alcohol dehydrogenase; antidiuretic hormone; arg... |
| AHU | acute hemolytic uremic [syndrome]; arginine, hypoxanthine, and uracil |
| AITT | arginine insulin tolerance test; augmented insulin tolerance test |
| ARG, Arg | arginine |
| arginine vasopressin | [8-arginine]vasopressin; [Arg8]vasopressin;vasopressin containing an arginyl residue in position 8 (as in chickens and most mammals, including man); porcine vasopressin has a lysyl residue at position 8. All are vasopressors. Synonym: argipressin. (05 Mar 2000) |
|---|---|
| arginine vasotocin | Vasotocin with arginyl residue at position 8 (identical with arginine oxytocin). See: arginine vasopressin. (05 Mar 2000) |
| beta-alanyl-arginine hydrolase | <enzyme> Also hydrolyzes carnosine, at a lower rate; requires mn2+; inhibited by bestatin; stabilised by sulfhydryl reagents Registry number: EC 3.4.13.- Synonym: ala-arg hydrolase (26 Jun 1999) |
| calcium-calmodulin-activated histone 3 arginine kinase | <enzyme> From nuclear extracts of dividing and quiescent rat heart endothelial cells; represents a new class of ca-cam-dependent kinases which phosphorylate arg Registry number: EC 2.7.10.- Synonym: ca(2+)-calmodulin-activated histone 3 arg kinase, ca-cam h3 kinase (26 Jun 1999) |
| complement 5a, des-arginine | Complement 5a with the carboxy-terminal arginine removed. The arginine is rapidly cleaved from the c5a fragment during complement activation by carboxypeptidase b present in normal human serum. C5a des-arg shows complete loss of spasmogenic activity though it retains some chemotactic ability. (12 Dec 1998) |
| protein-arginine n-methyltransferase | <enzyme> An enzyme that catalyses the methylation of arginine residues of proteins to yield n-mono- and n,n-dimethylarginine. This enzyme is found in many organs, primarily brain and spleen. Chemical name: S-Adenosyl-L-methionine:protein-L-arginine N-methyltransferase Registry number: EC 2.1.1.23 (12 Dec 1998) |
| NAD(p)-arginine ADP-ribosyltransferase | <enzyme> An enzyme that catalyses the transfer of the ADP-ribose moiety from NAD to specific protein substrates with agmatine, arginine-type compounds, or guanidine as acceptors. This reaction can be catalyzed by prokaryotic and eukaryotic enzyme systems. Mono-ADP-ribosylation is a mechanism of action common to several bacterial toxins. It effects profound changes in cellular metabolism, such as activation of adenylate cyclase, regulation of protein synthesis at the level of elongation factor 2, and ion transport across biological membranes. Chemical name: NAD(+)-L-arginine ADP-D-ribosyltransferase Registry number: EC 2.4.2.31 (12 Dec 1998) |
| N-arginine dibasic convertase | <enzyme> Catalyses cleavage at the n-terminus of arginine residues in dibasic stretches of proteins; located in brain cortex; genbank l27124 Registry number: EC 3.4.24.- Synonym: nrd convertase, n-arg dibasic convertase (26 Jun 1999) |
| anovulatory cycle | A sexual cycle in which no ovum is discharged. (05 Mar 2000) |
| Born-Haber cycle | <physics> This is a mathematical description of the relationship between the electron affinity, heats of atomisation, ionisation energy and lattice energy of ionic compounds. (09 Oct 1997) |
| bottoming cycle | A cogeneration system in which steam is used first for process heat and then for electric power production. (05 Dec 1998) |
| brain wave cycle | The complete upward and downward excursion of a single wave, complex, or impulse as seen on an electroencephalogram. (05 Mar 2000) |
| c3 cycle | <biochemistry> The part of the photosynthesis process where carbon dioxide is converted into three-carbon compounds, which can then be turned into six-carbon sugars. (07 Nov 1997) |
| c4 cycle | <plant biology> An alternative, very efficient pathway used by plants living in areas with low levels of carbon dioxide, to convert carbon dioxide into a form usable by the plants during photosynthesis. (09 Oct 1997) |
| Calvin Benson cycle | <biochemistry, plant biology> Metabolic pathway responsible for photosynthetic carbon dioxide fixation in plants and bacteria. The enzyme that fixes carbon dioxide is RuDP carboxylase. The cycle is the only photosynthetic pathway in C3 plants and the secondary pathway in C4 plants. The enzymes of the pathway are present in the stroma of the chloroplast. (18 Nov 1997) |
