  • Designer cells for enantioselective reduction of ketones and use thereof in efficient production of enantioenriched alcohols
    Patent number: 9790524
    Abstract: The present invention is to provide a preparation of variant recombinant whole cell biocatalysts, referred herein as “designer cells” having significantly enhanced carbonyl reductase activity for use in the efficient production of variant industrially important enantiomerically enriched alcohols. More specifically, the alcohol is optically pure ethyl (S)-4-chloro-3-hydroxybutyrate, which is useful as chiral building block and an intermediate for the production of hydroxymethylglutaryl-CoA (HMG-CoA) reductase inhibitors.
    Type: Grant
    Filed: April 17, 2014
    Date of Patent: October 17, 2017
    Assignee: COUNCIL OF SCIENTIFIC & INDUSTRIAL RESEARCH
    Inventors: Gautam Srivastava, Suneet Kaur, Ravinder Singh Jolly
