| enzyme regulation | <biochemistry> Control of the rate of a reaction catalyzed by an enzyme by some effector (e.g., inhibitors or activators) or by alteration of some condition (e.g., pH or ionic strength). (05 Mar 2000) |
|---|---|
| enzyme replacement therapy | A type of medical treatment for patients who lack an important enzyme, the missing enzyme is injected into the patient. (09 Oct 1997) |
| enzyme repression | The interference in synthesis of an enzyme due to the elevated level of an effector substance, usually a metabolite, whose presence would cause depression of the gene responsible for enzyme synthesis. (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) |
| enzyme-catalyzed ligation | <enzyme> An enzyme-mediated joining of phosphodiester linkage of two stretches of DNA or RNA, or of peptide linkage of two polypeptides. (05 Mar 2000) |
| enzyme-linked immunoabsorbent assay | <investigation> The enzyme-linked immunoabsorbent assay is serologic test used as a general screening tool for the detection of antibodies to the HIV virus. Reported as positive or negative. Since false positive tests due occur (for example recent flu shot), positives will require further evaluation using the western blot. ELISA technology links an a measurable enzyme to either an antigen or antibody. In this way, it can then measure the presence of an antibody or an antigen in the bloodstream. Acronym: ELISA (27 Sep 1997) |
| enzyme-linked immunosorbent assay | An immunoassay utilizing an antibody labelled with an enzyme marker such as horseradish peroxidase. While either the enzyme or the antibody is bound to an immunosorbent substrate, they both retain their biologic activity; the change in enzyme activity as a result of the enzyme-antibody-antigen reaction is proportional to the concentration of the antigen and can be measured spectrophotometrically or with the naked eye. Many variations of the method have been developed. (12 Dec 1998) |
| enzyme-multiplied immunoassay technique | A type of immunoassay in which the ligand is labelled with an enzyme, and the enzyme-ligand-antibody complex is enzymatically inactive, allowing quantitation of unlabelled ligand. The test uses antibodies that react only with the particular drug for which the sample is being tested. The antibodies attach themselves to the drug if it is present in the sample. It is not designed to measure amounts of the drug present, only to detect its presence or absence. It is used predominantly, but not exclusively, for the detection of drugs of abuse in the urine. See: competitive binding assay, enzyme-linked immunosorbent assay. (05 Mar 2000) |
| enzyme-substrate complex | A noncovalent complex of two molecules; often referring to the enzyme-substrate complex in an enzyme-catalyzed reaction. Compare: central complex, Michaelis complex. Synonym: enzyme-substrate complex. (05 Mar 2000) |
| enzymes, coenzymes, and enzyme inhibitors | Proteins or RNA that act as biological catalysts, their cofactors, and inhibitors. (12 Dec 1998) |
| enzymes, immobilised | Enzymes which are immobilised on or in a variety of water-soluble or water-insoluble matrices with little or no loss of their catalytic activity. Since they can be reused continuously, immobilised enzymes have found wide application in the industrial, medical and research fields. (12 Dec 1998) |
| enzymic | Relating to an enzyme. Synonym: enzymic. (05 Mar 2000) |
| enzymic process | Any chemical reaction or series of reactions catalysed by an enzyme. (09 Oct 1997) |
| enzymologist | A specialist in enzymology. (05 Mar 2000) |

| enzyme-linked immunosorbent assay |
A type of enzyme immunoassay (EIA) to determine the presence of antibodies to HIV in the blood or oral fluids. Repeatedly reactive (ie, two or more) ELISA test results should be validated with an independent supplemental test of high specificity. In the United States the validation test used most often is the Western Blot test.

| enzyme |
a biological catalyst. That is, a substance that increases the speed of a chemical reaction without being changed in the overall process. Enzymes are vitally important to the regulation of the chemistry of cells and organisms.
