Abstract
Disclosed is a newly-discovered and isolated enzyme which is a nicotinamide adenine dinucleotide (NAD.sup.+)-linked C.sub.3 -C.sub.6 secondary alcohol-specific dehydrogenase. This enzyme, in the presence of oxygen and NAD, is capable of converting C.sub.3 -C.sub.6 secondary alcohols to the corresponding methyl ketones. The purified enzyme has a molecular weight of 95,000 .+-. 3,000 dalton as determined by acrylamide gel electrophoresis and contains two zinc atoms per molecule of protein. Primary alcohols are not oxidized by this enzyme.
