Alcohol Dehydrogenase 6 (ADH6) is a member of the alcohol dehydrogenase family, which plays a crucial role in the metabolism of alcohols in the human body. This enzyme is encoded by the ADH6 gene and is classified as a Class V alcohol dehydrogenase. The recombinant form of this enzyme is produced using recombinant DNA technology, which allows for the expression of the human ADH6 protein in various host systems, such as Escherichia coli.
The ADH6 gene is located on chromosome 4 and encodes a protein that consists of 375 amino acids . The protein belongs to the zinc-containing alcohol dehydrogenase family and has a unique structure compared to other members of the ADH family . The enzyme contains multiple unique residues and structural properties that are not observed in other ADH proteins .
ADH6 is primarily expressed in the liver and stomach, with higher expression levels observed in the liver of both fetuses and adults . The enzyme catalyzes the NAD-dependent oxidation of primary alcohols to their corresponding aldehydes and secondary alcohols to their corresponding ketones . This activity is essential for the metabolism of various substrates, including ethanol, retinol, other aliphatic alcohols, hydroxysteroids, and lipid peroxidation products .
Recombinant human ADH6 protein is produced using Escherichia coli as the expression system . The recombinant protein is typically purified to a high degree of purity (>90%) and is suitable for various applications, including SDS-PAGE and mass spectrometry . The recombinant form of ADH6 allows researchers to study the enzyme’s structure, function, and role in various metabolic pathways in a controlled laboratory setting.
ADH6 has been associated with several diseases, including anterior dislocation of the lens and calvarial doughnut lesions with bone fragility . The enzyme is also involved in important metabolic pathways, such as the oxidation by cytochrome P450 and the pharmacodynamics of cyclophosphamide . Understanding the function and regulation of ADH6 can provide insights into its role in these diseases and pathways, potentially leading to the development of new therapeutic strategies.
