The nucleotide sequence of the alcohol dehydrogenase gene Adh71k has been determined. The Adh71k allele encodes the thermostable and multifunctional ADH-71k allozyme of Drosophila melanogaster. Comparison with the sequences of AdhS, AdhF, and AdhFChD reveals differences in the coding and noncoding regions of the gene. Conceptual translation of the Adh71k sequence indicates that ADH-71k shares w...

The purpose of this work was to develop and optimize a simple and suitable method to detect the potential inhibitory effect of drugs and medicines on alcohol dehydrogenase (ADH) activity in order to evaluate the possible interactions between medicines and alcohol metabolism. Commonly used medicines that are often involved in court litigations related with driving under the influence of alcohol ...

Many colonic aerobic bacteria possess alcohol dehydrogenase (ADH) activity and are capable of oxidizing ethanol to acetaldehyde. Accordingly, some ingested ethanol can be metabolized in the colon in vivo via the bacteriocolonic pathway for ethanol oxidation. By diminishing the amount of aerobic colonic bacteria with ciprofloxacin treatment, we recently showed that the bacteriocolonic pathway ma...

Nucleotide sequence data from the alcohol dehydrogenase (Adh) region of 18 isochromosomal strains of Drosophila pseudoobscura were used to determine whether the lack of amino acid polymorphism in ADH results from a low neutral mutation rate or a recent directional selection event. We estimated the neutral mutation parameter, 4Nmu, in synonymous sites for 17 subregions of Adh. The nucleotide div...

Sowing time of soybean (Glycine max [L.] Merr.) often coincides with the early onset of rainy season. Germinating seeds encounter a transient to prolonged period of water-logging that causes anoxia (absence of oxygen) and hypoxia (insufficient oxygen) resulting in poor germination. This reduces crop stability and yield. One of the factors responsible for flood tolerance is activity of alcohol d...

Natural variants displaying different levels of expression of the gene for alcohol dehydrogenase (Adh) were subjected to genetic mapping experiments. The strains studied carry one of the two common electrophoretic forms of the enzyme. The difference among Adh-fast strains appears to be due to multiple loci with trans-acting effects. Differences among Adh-slow strains are due to modifiers or qua...

The retention of the enzyme activity of alcohol dehydrogenase (ADH) has been studied in various drying processes such as spray drying. The aim of this study is to encapsulate ADH in mannitol, either with or without additive in order to limit the thermal denaturation of the enzyme during the drying process. The retention of ADH activity was investigated at different drying temperatures. When man...

Alcohol is eliminated from the body by various metabolic mechanisms. The primary enzymes involved are aldehyde dehydrogenase (ALDH), alcohol dehydrogenase (ADH), cytochrome P450 (CYP2E1), and catalase. Variations in the genes for these enzymes have been found to influence alcohol consumption, alcohol-related tissue damage, and alcohol dependence. The consequences of alcohol metabolism include o...

One of the key goals of enzymatic biofuel cells research has been the development of a fully enzymatic biofuel cell that operates under a continuous flow-through regime. Here, we present our work on achieving this task. Two NAD(+)-dependent dehydrogenase enzymes; malate dehydrogenase (MDH) and alcohol dehydrogenase (ADH) were independently coupled with poly-methylene green (poly-MG) catalyst fo...
