oxidation of a variety of structurally different ketones with notable activity and enantioselectivity, including the desymmetrization of 4-methylcyclohexanone (99% ee, S). In order to induce the reversal of enantioselectivity of this reaction as well as the transformations of other substrates, directedevolution based on iterative saturationmutagenesis (ISM) was applied, leading to (R)-selectivity (94%

substrate profile for structurally different cyclohexanones and cyclobutanones was assigned. The enzyme showed a lower activity than that of cyclohexanone monooxygenase (CHMOAcineto ) from Acinetobacter sp., as the prototype BVMO, but indicated higher kinetic stability by showing a twofold longer half-life at 30 °C. The thermodynamic stability, as represented by the melting temperature, resulted in a Tm value

terpenones and bicyclic ketones, as well as kinetic resolution of racemic cycloketones. We demonstrated the applicability of the title enzymes in the enantioselective synthesis of (R)-(-)-Taniguchi lactone, a buildingblock for the preparation of various natural product analogs such as ent-quinine.
