| RNA enzyme | <molecular biology> Often referred to as RNA with catalytic capacity, an enzyme made of nucleic acid not protein that catalyse chemical reactions, often the breakdown of other RNAs. Of particular interest because of the implications for self replicating systems in the earliest stages of the evolution of (terrestrial) life. Their discovery in the mid-1980s refuted the concept that only proteins could be biological catalysts. There is potential for their use as pharmaceuticals and industrial catalysts. (13 Nov 1997) |

| methionine-activating enzyme | <enzyme> An enzyme that catalyses the synthesis of s-adenosylmethionine from methionine and ATP. Chemical name: ATP:L-methionine S-adenosyltransferase Registry number: EC 2.5.1.6 (12 Dec 1998) |
| microparticle enzyme immunoassay | A technique in which the solid-phase support consists of very small microparticles in liquid suspension. Specific reagent antibodies are covalently bound to the microparticles. Antigen, if present, is then "sandwiched" between bound antibodies and antigen-specific, enzyme-labelled antibodies. Antigen-antibody complexes are detected and quantitated by analysis of fluorescence from the enzyme-substrate interaction. Acronym: MEIA (05 Mar 2000) |
| citrate cleavage enzyme | ATP citrate (pro-3S)-lyase |
| phosphorylase-rupturing enzyme | <enzyme> An enzyme that deactivates glycogen phosphorylase a by releasing inorganic phosphate and phosphorylase b, the inactive form. Chemical name: (Phosphorylase a) phosphohydrolase Registry number: EC 3.1.3.17 (12 Dec 1998) |
| photoreactivating enzyme | deoxyribodipyrimidine photolyase |
| 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 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) |
