    摘要: Disclosed are a ketoreductase mutant which can be used for an efficient production of daunorubicin derivatives, a DNA encoding the mutant, a transformant prepared by introducing the DNA thereinto to produce a daunorubicin derivative, and a process of producing a daunorubicin derivative using the transformant. The ketoreductase mutant has an amino acid sequence in which one amino acid residue or two or more amino acid residues selected from the group consisting of amino acids located at positions corresponding to the 42nd, 149th, 153rd, 270th, and 306th amino acids in the amino acid sequence of a ketoreductase (EvaE) from a chlororemomycin-producing bacterium (Amycolatopsis orientalis) are substituted with another amino acid residues.
