Patents by Inventor Dominique Gritscher

Dominique Gritscher 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).

  • Nucleic acid molecules encoding enzymes having fructosyl polymerase activity
    Patent number: 7153674
    Abstract: Described are nucleic acid molecules encoding enzymes having fructosyl polymerase activity. These enzymes are sucrose dependent sucrose fructosyltransferases (SST) enzymes. Furthermore, vectors and host cells are described containing the nucleic acid molecules, in particular transformed plant cells and plants that can be regenerated from them and that express the described SSTs. Furthermore, methods for the production of short-chain fructosyl polymers using the described hosts and/or the SSTs produced by them are described.
    Type: Grant
    Filed: November 14, 2002
    Date of Patent: December 26, 2006

  • Nucleic acid molecules which encode proteins having fructosyl transferase activity and methods for producing long-chain inulin
    Patent number: 7083963
    Abstract: Nucleic acid molecules are described encoding proteins with the enzymatic activity of a fructosyl transferase. These enzymes are fructosyl transferases (FFT). Moreover, vectors and host cells are described containing the nucleic acid molecules of the invention, in particular transformed plant cells, plant tissue and plants regenerable therefrom, which express the described FFT. Furthermore, methods for the production of long-chain inulin by using the described proteins, hosts, in particular the plant cells and/or FFT produced by them, are described.
