| butanol dehydrogenase | <enzyme> From clostridium acetobutylicum; reduces butyraldehyde to butanol; has higher activity on longer chain (c5,c6 or c7) aldehydes Registry number: EC 1.1.1.- Synonym: NADH-dependent butanol dehydrogenase (26 Jun 1999) |
|---|
| acetone-butanol fermentation | <biochemistry, microbiology> The formation of acetone and butanol through the fermentation of glucose by Clostridium acetobutylicum. However, most industrial plants make acetone and butanol through synthetic processes that use petrochemicals. (06 May 1997) |
|---|---|
| butanol | Preferred chemical name for n-butyl alcohol. (05 Mar 2000) |
| butanol, butyl alcohol | An alcohol with the chemical formula CH3(CH2)30H. It is formed during anaerobic fermentation using bacteria to convert the sugars to butanol and carbon dioxide. (05 Dec 1998) |
| butanol-extractable iodine | Iodine that can be separated from plasma proteins by butanol or other extractable solvents; used to measure thyroid function. (05 Mar 2000) |
| butanol-extractable iodine test | An obsolete test for thyroid function, applicable in patients who have received large amounts of iodine or iodised products. Synonym: BEI test. (05 Mar 2000) |
| acetaldehyde dehydrogenase | <enzyme> Works with both nad and nadp Registry number: EC 1.2.1.5 Synonym: aldehyde dehydrogenase (NADP+), naho gene product (26 Jun 1999) |
| acetoin dehydrogenase | <enzyme> An enzyme that catalyses the conversion of acetoin to diacetyl in the presence of NAD. Chemical name: Acetoin:NAD+ oxidoreductase Registry number: EC 1.1.1.5 (12 Dec 1998) |
| acetol dehydrogenase | <enzyme> Forms methylglyoxal; uses nad+ Registry number: EC 1.1.1.- Synonym: 1-hydroxyacetone dehydrogenase (26 Jun 1999) |
| acyl-ACP dehydrogenase | enoyl-ACP reductase (NADPH) |
| acyl-CoA dehydrogenase | <enzyme> See also records for specific fatty acyl groups which have full EC nomenclature number; electron-transferring flavoprotein system reducing ubiquinone and other acceptors; formerly EC 1.3.2.2 Registry number: EC 1.3.99.3 Synonym: fatty-acyl CoA dehydrogenase, palmitoyl-CoA dehydrogenase, short-chain acyl-CoA dehydrogenase, acyl-coenzyme a dehydrogenase, lauroyl-CoA oxidase (26 Jun 1999) |
| acyl-CoA dehydrogenase (NADPH+) | Enzyme catalyzing the reversible reduction of enoyl-CoA derivatives of chain length 4 to 16, with NADPH as the hydrogen donor, forming acyl-CoA and NADP+. Synonym: enoyl-CoA reductase. (05 Mar 2000) |
| alanopine dehydrogenase | <enzyme> Catalyses reductive elimination between pyruvate and alanine, or glycine, utilizing NADH as coenzyme, producing 2,2'-iminodipropionic acid (alanopine) Registry number: EC 1.5.1.- (26 Jun 1999) |
| alcohol dehydrogenase | <enzyme> An enzyme that catalyses reversibly the final step of alcoholic fermentation by reducing an aldehyde to an alcohol. In the case of ethanol, acetaldehyde is reduced to ethanol in the presence of NADH and hydrogen. The enzyme is a zinc protein which acts on primary and secondary alcohols or hemiacetals. Chemical name: Alcohol:NAD+ oxidoreductase Registry number: EC 1.1.1.1 (12 Dec 1998) |
| alcohol dehydrogenase (acceptor) | An oxidoreductase that reversibly converts primary alcohols to aldehydes with an H acceptor other than NADP+. (05 Mar 2000) |
| alcohol dehydrogenase (NADP+) | An oxidoreductase reversibly converting alcohols to aldehydes (or ketones) with NAD(P)+ as H acceptor. Synonym: aldehyde reductase, DPNH aldehyde transhydrogenase. (05 Mar 2000) |
