Coupled oxidoreductase activity of horse liver alcohol dehydrogenase
Archives of Biochemistry and Biophysics, 1972Abstract Two assay procedures were used to study ethanol oxidation by crystalline horse liver alcohol dehydrogenase: (A) Acetaldehyde formed by ethanol oxidation (with and without lactaldehyde) was distilled into a semicarbazide solution and the absorbance of the acetaldehyde semicarbazone formed was measured at 224 nm.

Aryl-alcohol oxidase (AAO), an FAD-dependent enzyme involved in lignin degradation, has been cloned from Pleurotus eryngii. The AAO protein is composed of 593 amino acids, 27 of which form a signal peptide. It shows 33% sequence identity with glucose oxidase from Aspergillus niger and lower homology with other oxidoreductases.

Microbial Alcohol, Aldehyde and Formate Ester Oxidoreductases
1993Formation of alcohols by natural processes takes place in the fermentative breakdown of sugars and the oxidative dissimilation of alkanes. In view of the wide-spreadness of these processes, it is understandable that many microbial species have the capacity to degrade these compounds.

Lignin biodegradation, a key step in carbon recycling in land ecosystems, is carried out by white-rot fungi through an H(2)O(2)-dependent process defined as enzymatic combustion. Pleurotus eryngii is a selective lignin-degrading fungus that produces H(2)O(2) during redox cycling of p-anisylic compounds involving the secreted flavoenzyme aryl-alcohol ...

Quinoprotein oxidoreductases for the oxidation of alcohols, sugars and amines
1994Quinoproteins are enzymes containing a quinone cofactor, that is the non-covalently bound PQQ or the protein-chain-integrated TPQ or TTQ. Quinoprotein dehydrogenases play a role in non-phosphorylative degradation of sugars, alcohols, aldehydes, ketones, and amines by Gram-negative bacteria, providing useful energy to the organism by their capacity to ...

Microbial Alcohol/Aldehyde Oxidoreductases in Enantioselective Conversions
1992Microbes have an enormous diversity of alcohol and aldehyde oxidoreductases. A brief overview is given of the types known and of some novel ones discovered recently. Except from the classical, NAD-dependent, alcohol dehydrogenase (the long chain, zinc-containing type, EC 1.1.1.1), these enzymes are unexplored with respect to enantioselectivity.

Alcohol dehydrogenases (ADHs) from thermophilic microorganisms are interesting enzymes that have their potential applications in biotechnology and potentially provide insight into the mechanisms of action of thermo-tolerant proteins. The molecular mechanisms of ADHs under thermal stress in vivo have yet to be explored.

Potential applications of an alcohol-aldehyde/ketone oxidoreductase from thermophilic bacteria
Enzyme and Microbial Technology, 1981Practical uses of a novel alcohol dehydrogenase from Thermoanaerobium brockii have been examined in crude and purified form. Stoichiometric reduction of NADP (50 mg) was demonstrated with agarose-immobilized enzyme and 0.3 (v/v) 2-propanol solution as reductant.

Pediatric Neurology, 1992
We report a boy and girl with a "new" multiple congenital anomalies/mental retardation syndrome which resemblances Sjögren-Larsson syndrome. Both patients had a concordant pattern of anomalies consisting of congenital lamellar ichthyosis with spontaneous improvement, moderate mental retardation, mild pyramidal involvement, telecanthus, flat facies ...

Abstract Nicotinamide adenine dinucleotide (NAD) is an important cofactor in a number of oxidoreductase enzyme systems. The detection and quantitation of its reduced form (NADH) is the basis for a number of methods which determine both substrates and enzyme activity.
