| glycine-rich beta-glycoprotein | <enzyme> A glycine-rich, heat-labile beta-glycoprotein found in blood. It is a proactivator of complement 3 in the alternate pathway of complement activation. Factor b is converted by factor d to c3 convertase. Registry number: EC 3.4.21.47 (12 Dec 1998) |
|---|---|
| glycine-rich beta-glycoproteinase | <enzyme> A serum protein which during the alternate pathway of complement activation converts the inactive properdin factor b to c3 convertase. Registry number: EC 3.4.21.46 (12 Dec 1998) |
| glycine-succinate cycle | A series of metabolic steps in which glycine is condensed with succinyl-CoA and is then oxidised to CO2 and H2O with regeneration of the succinyl-CoA; important in the synthesis of d-aminolevulinic acid and in the metabolism of red blood cells. Synonym: Shemin cycle. (05 Mar 2000) |
| glycine synthase | A complex of several proteins that catalyze the reversible reaction of glycine with tetrahydrofolate to produce CO2, NH3, and N5,N10-methylenetetrahydrofolate; a deficiency of this enzyme (or one of its subunits) will result in nonketotic hyperglycinaemia. Synonym: glycine synthase. (05 Mar 2000) |
| glycine transamidinase | <enzyme> An enzyme catalyzing the transfer of an amidine group from l-arginine to glycine, forming guanidinoacetate and l-ornithine; an important reaction in creatine synthesis; it can also act on canavanine. Synonym: glycine transamidinase. (05 Mar 2000) |
| glycine-trna ligase | <enzyme> An enzyme that activates glycine with its specific transfer RNA. Chemical name: Glycine:tRNA(Gly) ligase (AMP-forming) Registry number: EC 6.1.1.14 (12 Dec 1998) |
| basal medium | <cell culture> An unsupplemented medium which promotes the growth of many types of microorganisms which do not require any special nutrient supplements. (15 Nov 1997) |
| ganglion cervicale medium | A sympathetic ganglion, of small size and sometimes absent; located at the level of the cricoid cartilage. Synonym: ganglion cervicale medium. (05 Mar 2000) |
| ramus lateralis ramorum lobaris medium arteriorum pulmonalium dextrorum | Lateral branch of middle lobe branch of right pulmonary artery. See: lateral branches. (05 Mar 2000) |
| passive medium | A medium that produces no change in the specimens placed in it. (05 Mar 2000) |
| mediastinum medium | The central portion of the inferior mediastinum which contains the pericardium and its contents and the phrenic nerves and accompanying vessels. Synonym: mediastinum medium. (05 Mar 2000) |
| medium | <cell biology> Shorthand for culture medium or growth medium, the nutrient solution in which cells or organs are grown. (18 Nov 1997) |
| medium artery | <anatomy, artery> An artery with a tunica media composed principally of circularly arranged smooth muscle. Synonym: distributing artery, medium artery. (05 Mar 2000) |
| medium-chain acyl-CoA dehydrogenase | <enzyme> Deficiency in mitochondrial beta oxidation of fatty acids gives a disorder frequently masquerading as reye syndrome or sudden infant death; leads to buildup of octanoyl carnitine in urine Registry number: EC 1.3.- Synonym: mcaca-dehydrogenase, medium-chain acyl-coenzyme a dehydrogenase, octanoyl-CoA dehydrogenase, mcad enzyme (26 Jun 1999) |
| medium vein | <anatomy, vein> A vein characterised by having a thinner wall and larger lumen than its corresponding artery, and a media with small bundles of circular muscle separated by considerable connective tissue; valves also occur. (05 Mar 2000) |
