    摘要: Methods and devices for more efficiently engineering diversity into recombinant polypeptides and/or nucleic acids are provided herein. For example, a variety of methods of selecting and/or assessing potential crossover sites in an amino acid sequence or a nucleotide sequence are provided, as well as the resulting chimeric product sequences. These methods include, e.g., consideration of structural, functional and/or statistical data in the selection and assessment of sequences and crossover sites for use in recombination.

    摘要: The present disclosure provides engineered ketoreductase enzymes having improved properties as compared to a naturally occurring wild-type ketoreductase enzyme including the capability of reducing 5-((4S)-2-oxo-4-phenyl(1,3-oxazolidin-3-yl))-1-(4-fluorophenyl)pentane-1,5-dione to (4S)-3-[(5S)-5-(4-fluorophenyl)-5-hydroxypentanoyl]-4-phenyl-1,3-oxazolidin-2-one. Also provided are polynucleotides encoding the engineered ketoreductase enzymes, host cells capable of expressing the engineered ketoreductase enzymes, and methods of using the engineered ketoreductase enzymes to synthesize the intermediate (4S)-3-[(5S)-5-(4-fluorophenyl)-5-hydroxypentanoyl]-4-phenyl-1,3-oxazolidin-2-one in a process for making Ezetimibe.
