| a1AT | alpha-1-antitrypsin |
| glucan-1,4-glucosidase | <enzyme> An enzyme which removes the last 1,4-linked alpha-D- glucose residue from the nonreducing end of a long chain (or polymer) of such residues, making abeta-D-glucose molecule out of it in the process. (09 Oct 1997) |
|---|---|
| glucan endo-1,3-beta-d-glucosidase | <enzyme> An enzyme that hydrolyzes 1,3-beta-d-glucosidic linkages in 1,3-beta-d-glucans including laminarin, paramylon, and pachyman. Chemical name: 1,3-beta-D-Glucan glucanohydrolase Registry number: EC 3.2.1.39 (12 Dec 1998) |
| glucosidase | <enzyme> An enzyme catalysing the release of glucose by hydrolysis of the glycosidic link in various B D glucosides, R B D glucose, where the group R may be alkyl, aryl, mono or oligosaccharide. Favoured source: almonds, from which enzyme is known as emulsin. (18 Nov 1997) |
| glucosidase inhibitor | Agents such as acarbose which reduce gastrointestinal absorption of carbohydrates. This group of drugs has been known popularly as "starch blockers". They lower plasma glucose levels and tend to cause weight loss. A limiting side effect is flatulence. (05 Mar 2000) |
| oligo-1,6-glucosidase | <enzyme> An enzyme that catalyses the endohydrolysis of 1,6-alpha-glucosidic linkages in isomaltose and dextrins produced from starch and glycogen by alpha-amylase. Chemical name: Dextrin 6-alpha-D-glucanohydrolase Registry number: EC 3.2.1.10 (12 Dec 1998) |
| oligo-a1,6-glucosidase | A glucanohydrolase cleaving alpha-1,6 links in isomaltose and dextrins produced from starch and glycogen by alpha-amylase; secreted into the duodenum; a deficiency of this enzyme leads to defects in intestinal digestion of limit dextrins. See: sucrose alpha-d-glucohydrolase. Synonym: isomaltase, limit dextrinase. (05 Mar 2000) |
| 4-methylumbelliferyl-beta-glucosidase | <enzyme> Aspect of EC 3.2.1.21 Registry number: EC 3.2.1.- (26 Jun 1999) |
| 6-ethanoylamino-4-methylumbelliferyl-beta-glucosidase | <enzyme> A soluble lysosomal enzyme with a discrete isoelectric point of about 5.0; hydrolyzes 6-ethanoylamino-4-methylumbelliferyl-beta-d-glucoside Registry number: EC 3.2.1.- Synonym: emglc-ase (26 Jun 1999) |
| 6-phospho-beta-glucosidase | <enzyme> Catalyses the conversion of 6-phospho-beta-d-glucosyl-(1,4)-d-glucose and h2o to d-glucose-6-phosphate and d-glucose; do not confuse with bgla gene product from rhodothermus which catalyses the reaction of EC 3.2.1.39 (endo-1,3-beta-glucanase) Registry number: EC 3.2.1.86 Synonym: bgla gene product, bglh gene product, glvg gene product (26 Jun 1999) |
| furostanol glycoside 26-O-beta-glucosidase | <enzyme> From costus speciosus rhizomes; specifically cleaves the c-26-bound glucose moiety of furostanol glycosides Registry number: EC 3.2.1.- Synonym: f26g enzyme (26 Jun 1999) |
| acetyl-CoA:alpha-glucosaminide acetyltransferase | <enzyme> An enzyme involved in the synthesis of certain carbohydrate moieties on proteins. A deficiency of this enzyme leads to mucopolysaccharidosis type III C. (05 Mar 2000) |
| adrenergic alpha-agonists | Drugs that selectively bind to and activate alpha adrenergic receptors. (12 Dec 1998) |
| adrenergic alpha-antagonists | Drugs that bind to but do not activate alpha-adrenergic receptors thereby blocking the actions of endogenous or exogenous adrenergic agonists. Adrenergic alpha-antagonists are used in the treatment of hypertension, vasospasm, peripheral vascular disease, shock, and pheochromocytoma. (12 Dec 1998) |
| alpha | First letter of the Greek alphabet, a. (05 Mar 2000) |
| alpha-1,3-mannosylglycoprotein beta-1,4-N-acetylglucosaminyltransferase | <enzyme> Incorporates n-acetyglucosamine as the third branch of complex n-glycosyl-oligosaccharide of hen oviduct Registry number: EC 2.4.1.145 Synonym: glcnac-transferase iv, n-acetylglucosaminyltransferase iv, udp-glcnac-gngn(glcnac to man alpha1-3)beta 4-n-acetylglucosaminyltransferase iv (26 Jun 1999) |
