| modification enzyme | <enzyme, molecular biology> An enzyme that introduces minor bases into DNA or RNA or that alters bases already incorporated. Serves to alter the sequence so that restriction enzymes will not damage the strand. (18 Nov 1997) |

| Warburg's old yellow enzyme | <enzyme> A flavoprotein that reversibly oxidises NADPH to NADP and a reduced acceptor. Chemical name: NADPH:(acceptor) oxidoreductase Registry number: EC 1.6.99.1 (12 Dec 1998) |
| Warburg's respiratory enzyme | 1. A system of cytochromes and their oxidases that participate in respiratory processes. 2. Often, specifically, cytochrome oxidase. Synonym: Warburg's respiratory enzyme. Origin: Ger. (05 Mar 2000) |
| co-immobilised enzyme | <biochemistry> A group of enzymes which work together and are physically confined while doing so. (09 Oct 1997) |
| cold sensitive enzyme | <enzyme> An enzyme that loses its stability as the temperature is lowered. (05 Mar 2000) |
| condensing enzyme | Citrate (si)-synthase;an enzyme catalyzing the condensation of oxaloacetate, water, and acetyl-CoA, forming citrate and coenzyme A; an important step in the tricarboxylic acid cycle. Synonym: citrogenase, condensing enzyme, oxaloacetate transacetase. (05 Mar 2000) |
| multi locus enzyme electrophoresis | Inhibition of translation of the transcript of a transposase gene by a multicopy plasmid with suitable inhibitory gene. The plasmid inhibits transposition events in the host bacterium. (18 Nov 1997) |
| constituent enzyme | <biochemistry> Any of many enzymes that a cellmust have at all times to stay alive. (09 Oct 1997) |
| constitutive enzyme | <enzyme> An enzyme that is constantly produced by the cell regardless of the growth conditions. Compare: induced enzyme. (05 Mar 2000) |
| cooperative enzyme | <enzyme> An enzyme that exhibits the property of cooperativity. (05 Mar 2000) |
| coordinated enzyme synthesis | The regulatory mechanism where an entire group of different enzymes, all of which play a part in the same metabolic process, is synthesised at the same time. This comes about because the chemical signal to begin synthesis of each enzyme is the same for all of them. (09 Oct 1997) |
| heat-stable enzyme | <enzyme> An enzyme that is not readily subject to destruction or alteration by heat. Synonym: heat-stable enzyme. (05 Mar 2000) |
| Schardinger enzyme | <enzyme> Dehydrogenases involved in conversion of hypoxanthine to xanthine and xanthine to uric acid, as the final catabolism of purines. Deficient in the human disease xanthinuria. (18 Nov 1997) |
| proteolytic enzyme | <enzyme> See protease or peptidase. (18 Nov 1997) |
| heterotrophic enzyme | <biochemistry> An allosteric enzyme that must be modulated by a biomolecule other than its substrate. (09 Oct 1997) |
