Zusammenfassung:The present invention relates to a production method of an enantiomer-enriched compound, which includes the following (1) and (2): (1) contacting an enantiomer mixture with a stereoselective dehydrogenase, for which NAD+ (nicotinamide adenine dinucleotide) is a coenzyme, thereby preferentially oxidizing one enantiomer and leaving the other enantiomer to form NADH, and (2) contacting the NADH formed by the oxidation reaction in (1) with a water-forming NADH oxidase stable under oxidative conditions to convert the NADH to NAD+. According to the present invention, in the production of an enantiomer-enriched compound from an enantiomer mixture, which uses a dehydrogenase, NAD+ can be regenerated even without addition of a stabilizer and an enantiomer-enriched compound can be obtained efficiently.
