Abstract
To provide a method for preparing optically active compounds, which mainly contain (R)-amino compounds, by microbial enzymes efficiently and inexpensively; a polypeptide having stereoselective transaminase activity which can be suitably used for the above preparation method; and a DNA encoding the polypeptide. A method for preparing an optically active amino compound, characterized in stereoselectively transaminating by acting a transaminase on an amino group acceptor, a ketone compound in the presence of an amino group donor, a primary amine; a DNA comprising a nucleotide sequence encoding a polypeptide having stereoselective transaminase activity; and a polypeptide having stereoselective transaminase activity obtainable from a culture of a microorganism belonging to the genus Arthrobacter.
