| lactose-litmus agar | Agar made by adding 2% lactose and litmus to acid-free nutrient agar; formerly used in the identification of Salmonella typhi. (05 Mar 2000) |

| lactose operon | Group of adjacent and coordinately controlled genes concerned with the metabolism of lactose in E. Coli. The lac operon was the first example of a group of genes under the control of an operator region to which a lactose repressor binds. When the bacteria are transferred to lactose containing medium, allolactose (which forms by transglycosylation when lactose is present in the cell) binds to the repressor, inhibits the binding of the repressor to the operator and allows transcription of mRNA for enzymes involved in galactose metabolism and transport across the membrane (_ galactosidase, galactoside permease and thiogalactoside transacetylase). (18 Nov 1997) |
| lactose permease | <chemical> Chemical name: permease, lactose Synonym: lactose carrier protein, lactose permease m protein, lac permease, lactose transport protein, lactose transport system, lac carrier protein, lacs protein, lactose transport system, streptococcus thermophilus, lacy protein (26 Jun 1999) |
| lactose repressor | Protein (tetramer of 37 kD subunits) that normally binds with very high affinity to the operator region of the lactose operon and inhibits transcription of the downstream genes by blocking access of the polymerase to the promoter region. When the lactose repressor binds allolactose, its binding to the operator is reduced and the gene set is derepressed. (18 Nov 1997) |
| lactose synthase | <enzyme> An enzyme of the transferase class that catalyses the transfer of galactose from udpgalactose to glucose, forming lactose. The enzyme is a complex of the enzyme n-acetyllactosamine synthase and alpha-lactalbumin; the latter protein is present in lactating mammary gland cells where it alters the usual specificity of the former to make lactose synthesis the preferred reaction. Chemical name: UDPgalactose:D-glucose 4-beta-D-galactosyltransferase Registry number: EC 2.4.1.22 (12 Dec 1998) |
| amalgam carrier | An instrument used to transport triturated amalgam to a cavity preparation and to deposit it therein. (05 Mar 2000) |
| galactose-diphosphoglycosyl carrier lipid synthetase | <enzyme> Catalyses synthesis of gcl-pp-gal from udp gal and p-gcl; also catalyses exchange between the uridylyl moiety of udpgal and ump Registry number: EC 2.4.1.- (26 Jun 1999) |
| manifesting carrier | An organism heterozygous for what is ordinarily a recessive condition which, as a result of special mechanisms (such as lyonization, allelic exclusion, or a deletion in the homologous chromosome), has phenotypic manifestations. Synonym: manifesting carrier. (05 Mar 2000) |
| genetic carrier | An unaffected heterozygote bearing a usually harmful recessive gene, a cancer that bears a dominant but latent age-dependent trait to have offspring with unbalanced karyotypes. (05 Mar 2000) |
| carrier | 1. <genetics, microbiology> An individual who does not display the symptoms of a disease, but harbors the pathogen which causes it, or has the gene (or genes) for it, and can transmit the disease to others either through interacting with other individuals, or by passing the disease-causing gene (or genes) to offspring. 2. <pharmacology> A substance which transports things, such as a carrier protein. (09 Oct 1997) |
| carrier cell | <cell biology> A cell that is capable of phagocytosis. The main mammalian phagocytes are neutrophils and macrophages. Origin: L. Phagedaena, Gr Phago, To eat. (18 Nov 1997) |
| carrier electrophoresis | Electrophoresis done on a carrier (such as paper, polyacrylamide gel, etc.). (05 Mar 2000) |
| carrier-free | A substance in which a radioactive or other tagged atom is found in every molecule; the highest possible specific activity. (05 Mar 2000) |
| 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.
