| enzyme |
An enzyme (in Greek en = in and zyme = leaven) is a protein, or protein complex, that catalyzes a chemical reaction and also controls the 3D orientation of the catalyzed substrates. Like any catalyst, enzymes work by lowering the activation energy of a reaction, thus allowing the reaction to proceed to its steady state or completion much faster than it otherwise would; the enzyme (again, as with any catalyst) remains unaltered by the completed reaction and can therefore continue catalysis. ...

| enzyme activity |
the catalytic effect exerted by an enzyme, expressed as units per milligram of enzyme (specific activity) or as molecules of substrate transformed per minute per molecule of enzyme (molecular activity). The conventional unit of enzyme activity is the International Unit (IU), equal to one micromole of substrate transformed per minute. A proposed coherent Syst?e Internationale (SI) unit is the katal (kat), equal to one mole of substrate transformed per second.

| Enzyme Commission |
(EC) Number Systematic name and number which identify an enzyme in technical literature. Assigned by the Enzyme Commission, the EC Number consists of four numbers separated by dots: the first classifies the enzyme into one of the six broad groups: 1. Oxidoreductase; 2. Transferases; 3. Hydrolases; 4. Lyases; 5. Isomerases; 6. Ligases. Each group is subdivided into sub-groups, each sub-group into sub-sub-groups, and the last number is specific for the enzyme, eg, EC 3.1. ...

| enzyme-linked immunosorbent assay |
A widely used immunochemical method for detecting antigens or antibodies. ELISA methods are carried out in microtitre plates and use colorimetric detection.
