Holger Lüttgen 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).

  • Isoprenoid biosynthesis
    Patent number: 7534742
    Abstract: The present invention relates to enzymatic activity involved in isoprenoid biosynthesis as well as to inhibitors, notably herbicides, for enzymes in the biosynthesis of isoprenoids. More specifically, the present invention relates to screening methods for detecting such inhibitors, and to enzymatically active proteins for performing said methods as well as purified isolated DNA coding for such proteins. Moreover, the present invention relates to novel inhibitors detectable by said screening methods as well as compositions and processes for inhibiting the synthesis of isoprenoids and for controlling the growth of organisms based on said inhibitors. The invention relates also to the development of inhibitor-resistant plant enzymes and plants, plant tissues, plant seeds and plant cells.
    Type: Grant

  • Riboflavin production
    Patent number: 6376222
    Abstract: The present invention provides a transformed yeast strain containing a DNA sequence transcriptionally linked to a promoter functional in such yeast cells, which when expressed in a suitable host cell, encodes at least one polypeptide having riboflavin biosynthetic activity. Using such transformants, improved levels of riboflavin production are achieved. Processes of producing riboflavin from such transformants are also provided.
