A shuttle vector is constructed by preparing a DNA region replicable in bacteria belonging to the genus Rhodococcus from a Rhodococcus-derived plasmid having the nucleotide sequence set forth as SEQ ID NO: 73 and a plasmid or its DNA fragment having the nucleotide sequence set forth as SEQ ID NO: 74, and a DNA region replicable in E. coli from an E. coli-derived plasmid or its DNA fragment. An aminoketone asymmetric reductase gene is inserted into the shuttle vector, transformants containing the vector are created, and the aminoketone asymmetric reductase and optically active aminoalcohols are produced.
通过从具有 SEQ ID NO: 73 所列核苷酸序列的 Rhodococcus 衍生质粒和具有 SEQ ID NO: 74 所列核苷酸序列的质粒或其 DNA 片段中制备可在 Rhodococcus 属细菌中复制的 DNA 区域,以及从大肠杆菌衍生质粒或其 DNA 片段中制备可在大肠杆菌中复制的 DNA 区域,构建穿梭载体。将氨基酮不对称还原酶基因插入穿梭载体,产生含有该载体的转化体,并生产出氨基酮不对称还原酶和光学活性氨基醇。
