    • A process for preparing optically active alkanols of the formula I in which n is an integer from 0 to 5; Cyc is an optionally substituted, mono- or polynuclear, saturated or unsaturated, carbocyclic or heterocyclic ring, and R1 is halogen, SH, OH, NO2, NR2R3 or NR2R3R4+X−, with R2, R3 and R4 independently of one another being hydrogen or a lower alkyl or lower alkoxy radical and X− being a counterion, which process comprises incubating in a medium comprising alkanone of the formula II  in which n, Cyc and R1 are as defined above, an enzyme having a polypeptide sequence (i) SEQ ID NO: 1 or (ii) in which, compared to SEQ ID NO:1, up to 25% of the amino acid radicals have been altered by deletion, insertion, substitution or a combination thereof and which retains at least 50% of the enzymic activity of SEQ ID NO:1, with the compound of the formula II being enzymically reduced to give the compound of the formula I, and isolating the product formed.
    • 一种制备式I的光学活性链烷醇的方法,其中n为0至5的整数; Cyc是任选取代的单或多核饱和或不饱和的碳环或杂环,R1是卤素,SH,OH,NO2,NR2R3或NR2R3R4 + X-,R2,R3和R4彼此独立地是氢 或低级烷基或低级烷氧基,X是抗衡离子,该方法包括在包含式II的烷酮的培养基中孵育,其中n,Cyc和R 1如上定义,具有多肽序列(i)SEQ ID NO: SEQ ID NO:1或(ii)其中与SEQ ID NO:1相比,通过缺失,插入,取代或其组合改变多达25%的氨基酸基团,并且其保留至少50%的 酶活性为SEQ ID NO:1,其中式II化合物被酶还原,得到式I化合物,并分离形成的产物。
