Alcohol Dehydrogenase (from Yeast), MP Biomedicals

Supplier: MP Biomedicals

Alcohol dehydrogenases are a group of dehydrogenase enzymes that occur in many organisms. It is a metalloenzyme containing four tightly bound zinc atoms per molecule. Each subunit also contains a second zinc atom (conformational zinc), which stabilizes the enzyme’s tertiary structure. Per subunit, there are two distinct active site sulfhydryl groups which can be distinguished on the basis of differential reactivity with iodoacetate and butyl isocyanate. A histidine residue is considered to have an essential role.
