摘要 |
The invention relates to a method for preparing optically active 2-hydroxy acid ester derivatives of the formula R1-C(OH)-C(O)-O-R2 (I),comprising the bringing into contact of 2-oxo acid ester derivatives of the formula R1-C(O)-C(O)-O-R2 (II) with an enzyme (E) selected from the class of dehydrogenases, in the presence of reduction equivalents, where the compound of the formula (II) is enzymatically reduced to the compound of the formula (I), and the reduction equivalents consumed in the course of the reaction are regenerated again by converting a reducing agent (RA) to the corresponding oxidation product (OP) with the help of the enzyme (E). The invention further comprises a dehydrogenase which reduces 2-oxo acid esters in the presence of reduction equivalents to the corresponding S- 2-hydroxy acid esters, and also a nucleic acid encoding the dehydrogenase. |
