| enzymes, coenzymes, and enzyme inhibitors | Proteins or RNA that act as biological catalysts, their cofactors, and inhibitors. (12 Dec 1998) |
|---|---|
| enzyme stabilisation | Reducing the chances that an enzyme will inactivate in vitro (see enzyme inactivation) by changing the environmental conditions (such as pH, temperature, concentration of salt, etc.) or by attaching organic groups to it or changing some of its amino acid subunits. (09 Oct 1997) |
| enzyme stability | The extent to which an enzyme retains its structural conformation or its activity when subjected to storage, isolation, and purification or various other physical or chemical manipulations, including proteolytic enzymes and heat. (12 Dec 1998) |
| extracellular enzyme | <enzyme> An enzyme performing its functions outside a cell; e.g., the various digestive enzyme's. Synonym: exoenzyme, lyoenzyme. (05 Mar 2000) |
| yellow enzyme | Any enzyme that possesses a flavin nucleotide as coenzyme; e.g., xanthine oxidase, succinate dehydrogenase. Synonym: yellow enzyme. (05 Mar 2000) |
| UDP-N-acetylglucosamine-lysosomal-enzyme-N-acetylglucosaminephosphotransferase | <enzyme> Fibroblasts from patients with i-cell (mucolipidosis II) and pseudo-hurler polydystrophy (mucolipidosis III) are deficient in above enzyme; for n-acetylglucosamine transferred to dolichyl phosphate see EC 2.7.8.15 Registry number: EC 2.7.8.17 Synonym: udpgnac gp gnac phosphotransferase, udpgnac phosphotransferase, uridine 5'-diphosphate-n-acetylglucosamine glycoprotein n-acetylglucosaminylphosphotransferase, n-acetylglucosamine-1-phosphotransferase, n-agapt, udp-n-acetylglucosamine-lysosomal glycoprotein n-acetylglucosaminylphosphotransferase, udp-acetylglucosamine-glycoprotein n-acetylglucosamine-1-phosphotransferase (26 Jun 1999) |
| UDP-N-acetylglucosamine:lysosomal enzyme N-acetylglucosaminyl-1-phosphotransferase | <enzyme> An enzyme that participates in the posttranslational modification of a number of lysosomal proteins; a deficiency or defect in this enzyme results in two forms of mucolipidoses, I-cell disease, and pseudo-Hurler polydystrophy. (05 Mar 2000) |
| Kornberg enzyme | DNA polymerase I from Escherichia coli. (05 Mar 2000) |
| 1,4-alpha-glucan branching enzyme | <enzyme> In glycogen or amylopectin synthesis, the enzyme that catalyses the transfer of a segment of a 1,4-alpha-glucan chain to a primary hydroxy group in a similar glucan chain. Chemical name: 1,4-alpha-D-Glucan:1,4-alpha-D-glucan 6-alpha-D-(1,4-alpha-D-glucano)-transferase Registry number: EC 2.4.1.18 (12 Dec 1998) |
| liver enzyme | <biochemistry> Special proteins found in the cells of the liver that are responsible for catalysing specific metabolic reactions. They may become elevated in the bloodstream in conditions of hepatitis or liver cancer. See: liver function tests. (27 Sep 1997) |
| lysosomal enzyme | <biochemistry> A range of degradative enzymes, most of which operate best at acid pH. The best known marker enzymes are acid phosphatase and glucuronidase, but many others are known. (18 Nov 1997) |
| aberrant complex | An anomalous electrocardiographic complex, more specifically an abnormal ventricular complex caused by abnormal intraventricular conduction of a supraventricular impulse. (05 Mar 2000) |
| activated complex | <chemistry> State of highest energy during a reaction. When reactants form the activated complex, bond breaking and bond formation is occurring. Synonym: transition state. (09 Jan 1998) |
| AIDS dementia complex | <immunology> A frequent cerebral condition in people with AIDS that results in the loss of cognitive capacity, affecting the ability to function in a social or occupational setting. Its cause has not been determined exactly, but may result from HIV infection of cells in the brain or an inflammatory reaction to such infection. (09 Oct 1997) |
| aids-related complex | A prodromal phase of infection with the human immunodeficiency virus (HIV). Laboratory criteria separating aids-related complex (arc) from aids include elevated or hyperactive B-cell humoral immune responses, compared to depressed or normal antibody reactivity in aids; follicular or mixed hyperplasia in arc lymph nodes, leading to lymphocyte degeneration and depletion more typical of aids; evolving succession of histopathological lesions such as localization of kaposi's sarcoma, signaling the transition to the full-blown aids.
