Patents by Inventor Anke Kebber

Anke Kebber has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Glucose dehydrogenase polypeptides and related polynucleotides
    Patent number: 7816111
    Abstract: The present invention is directed to glucose dehydrogenase (GDH) polypeptides that have enhanced GDH activity and/or thermostability relative to the backbone wild-type glucose dehydrogenase polypeptide. In addition, the present invention is directed to a polynucleotide that encodes for the GDH polypeptides of the present invention, to nucleic acid sequences comprising the polynucleotides, to expression vectors comprising the polynucleotides operatively linked to a promoter, to host cells transformed to express the GDH polypeptides, and to a method for producing the GDH polypeptides of the present invention.
    Type: Grant
    Filed: August 11, 2004
    Date of Patent: October 19, 2010
    Assignee: Codexis, Inc.
    Inventors: S. Christopher Davis, Stephane J. Jenne, Anke Kebber, Lisa Marie Newman
  • Ketoreductase polypeptides and related polynucleotides
    Patent number: 7629157
    Abstract: The present invention is directed to variant polypeptides having enhanced ketoreductase activity and/or thermostability for use in the stereospecific reduction of ketones. In addition, the present invention is directed to polynucleotides that encode the ketoreductase polypeptides, including codon optimized versions of the polynucleotides which provide for enhanced expression in host cells. In another aspect, the present invention is directed to nucleotide constructs, vectors and host cells that are transformed with polynucleotides of the present invention.
