General description

Research Area: Neuroscience
Alcohol dehydrogenase is a zinc metalloprotein that forms five classes of isoenzymes through the dimerization of eight different subunits.

Application

Alcohol Dehydrogenase equine has been used in in vitro alcohol dehydrogenase (Adh) assay.

Biochem/physiol Actions

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 site for the alcohol substrate.
Horse liver alcohol dehydrogenase (HL-ADH) is an enzyme with broad specificity, capable of catalyzing the reversible oxidation of a wide variety of primary and secondary alcohols to form their corresponding aldehydes and ketones. Moreover, alcohol dehydrogenase can oxidize ethanol while simultaneously reducing nicotinamide adenine dinucleotide (NAD+) to NADH. Previous studies have demonstrated that ADH and ALDH variants can influence alcohol dependence. Additionally, the ADH genotype has been linked to lacunar infarction and neuropsychiatric diseases.

Unit Definition

1 U corresponds to the amount of enzyme which reduces 1 μmol benzaldehyde per minute at pH 7.0 and 30 °C.
