Stereospecific alcohol dehydrogenase isolated from Candida parapsilosis, amino acid and DNA sequences therefor, and method of preparation thereof

摘要

The present invention provides a novel secondary alcohol dehydrogenase useful for the synthesis of optically active alcohol and DNA encoding said enzyme. A microorganism belonging to genus Candida was found to produce a novel secondary alcohol dehydrogenase with a high stereochemical specificity. Using said enzyme, optically active alcohols were prepared, and by cloning of DNA encoding said enzyme, the base sequence of said DNA was determined. By providing a novel secondary alcohol dehydrogenase with a high stereochemical specificity and the gene encoding said enzyme, an efficient production of optically active alcohols became possible.
