Alcohol dehydrogenase catalyzes the oxidative conversion of alcohol into aldehyde. It has a homodimeric structure with a co-enzyme binding domain at the C-terminal and an N-terminal catalytic domain. The active site is located at the interdomain cleft. Binding of NAD+ in the active site causes conformational changes which create the binding sit for the alcohol substrate.
Unit Definition
1 U corresponds to the amount of enzyme which reduces 1 μmol benzaldehyde per minute at pH 7.0 and 30°C.
The gene encoding a novel short-chain alcohol dehydrogenase in the thermophilic bacterium, Carboxydothermus hydrogenoformans, was identified and overexpressed in Escherichia coli. The enzyme was thermally stable and displayed the highest activity at 70 °C and pH 6.0. It preferred NAD(H) over

Charge detection mass spectrometry (CDMS) measurements have been performed for cytochrome c and alcohol dehydrogenase (ADH) monomer using a modified cone trap incorporating a cryogenically cooled JFET. Cooling the JFET increases its transconductance and lowers thermal noise, improving the signal

In yeast, Adh1 (alcohol dehydrogenase 1) is an abundant zinc-binding protein that is required for the conversion of acetaldehyde to ethanol. Through transcriptome profiling of the Schizosaccharomyces pombe genome, we identified a natural antisense transcript at the adh1 locus that

3-n-Butylphthalide (NBP) is a cardiovascular drug currently used for the treatment of cerebral ischemia. The present study aims to investigate the metabolism, pharmacokinetics, and excretion of NBP in humans and identify the enzymes responsible for the formation of major metabolites.
The dynamics of proteins, detected by fluorescence, consists of three components: spontaneous dynamics, dipole-dipole photo-induced dynamics, thermal photo-induced dynamics. The photo-induced dynamics can lead to activation as well as inactivation of enzymes.
