| carrier protein | <protein> A protein which transports specific substances through the cell membrane in which it is embedded and into the cell. Different carrier proteins are required to transport different substances, as each one is designed to recognise only one substance, or group of similar substances. (09 Oct 1997) |
|---|---|
| carrier proteins | Transport proteins that carry specific substances in the blood or across cell membranes. (12 Dec 1998) |
| carrier screening | Indiscriminate examination of members of a population to detect heterozygotes for serious disorders and counsel about the risks of marriages with other carriers, and by antenatal diagnosis where a married couple are both carriers; often sacrifices precision to simplicity and is most effectively applied to populations known to be at high risk. (05 Mar 2000) |
| carrier strain | A bacterial strain that is contaminated with a bacteriophage of low infectivity. Synonym: pseudolysogenic strain. (05 Mar 2000) |
| carrier test | A test designed to detect carriers of a gene for recessive genetic disorder. For example, carrier testing is done for sickle cell trait, thalassaemia trait, and the Tay-Sachs gene. (12 Dec 1998) |
| mobile ion carrier | <chemistry> A molecule that allows ions to cross lipid bilayers. There are two classes: carriers and channels. Carriers, like valinomycin, form cage like structures around specific ions, diffusing freely through the hydrophobic regions of the bilayer. Channels, like gramicidin, form continuous aqueous pores through the bilayer, allowing ions to diffuse through. See: ion channels. (18 Nov 1997) |
| convalescent carrier | An individual who is clinically recovered from an infectious disease but is still capable of transmitting the infectious agent to others. (05 Mar 2000) |
| hydrogen carrier | A molecule that, in conjunction with a tissue enzyme system, carries hydrogen from one metabolite (oxidant) to another (reductant) or to molecular oxygen to form H2O. Synonym: hydrogen acceptor. (05 Mar 2000) |
| incubatory carrier | An individual capable of transmitting an infectious agent to others during the incubation period of the disease. (05 Mar 2000) |
| Tay-Sachs carrier | <genetics> One who carries the recessive gene that is responsible for Tay-Sachs disease. Genetic testing for this fatal disease is crucial so that Tay-Sachs carriers can be identified and provided with genetic counseling. (27 Sep 1997) |
| electron carrier | <chemistry> A protein which can either accept or donate electrons in oxidation-reduction reactions. (19 Jan 1998) |
| translocation carrier | A person with balanced translocation. (05 Mar 2000) |
| ubiquitin carrier protein kinase | <enzyme> A 300 kD kinase consisting of 3 subunits of mws 70, 105 and 120; requires magnesium but inhibited by high concentration; from hela cells Registry number: EC 2.7.10.- (26 Jun 1999) |
| lactose carrier protein | <protein> The best known example is the product of the lacY gene, coded for in the lactose operon and responsible for the uptake of lactose by E. Coli. (18 Nov 1997) |
| 3-oxoacyl-(acyl-carrier-protein) synthase | <enzyme> An enzyme of long-chain fatty acid synthesis, that adds a two-carbon unit from malonyl-(acyl carrier protein) to another molecule of fatty acyl-(acyl carrier protein), giving a beta-ketoacyl-(acyl carrier protein) with the release of carbon dioxide. Chemical name: Acyl-(acyl carrier protein):malonyl-(acyl-carrier-protein) C-acyltransferase (decarboxylating) Registry number: EC 2.3.1.41 (12 Dec 1998) |
