Sabine Breinig 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).

  • DNA and amino acid sequences of a tyrosine-inducible tyrosine ammonia lyase enzyme from the yeast Trichosporon cutaneum
    Patent number: 6951751
    Abstract: A novel tyrosine-inducible tyrosine ammonia lyase enzyme was isolated from the yeast Trichosporon cutaneum. This enzyme has a higher activity for tyrosine than for phenylalanine and is useful for the production of para-hydroxycinnamic acid directly from tyrosine. The gene encoding this enzyme was sequenced using 3? and 5? RACE cloning of the TAL cDNA and the gene was expressed in the yeast Saccharomyces cerevisiae and in the bacterium Escherichia coli.
    Type: Grant
    Filed: May 16, 2003
    Date of Patent: October 4, 2005
    Assignee: E. I. du Pont de Nemours and Company
    Inventors: Sabine Breinig, Wei Wei Qi, Fateme Sima Sariaslani, Todd M. Vannelli, Zhixiong Xue

    Publication number: 20040023357
    Abstract: A novel tyrosine-inducible tyrosine ammonia lyase enzyme was isolated from the yeast Trichosporon cutaneum. This enzyme has a higher activity for tyrosine than for phenylalanine and is useful for the production of para-hydroxycinnamic acid directly from tyrosine. The gene encoding this enzyme was sequenced using 3′ and 5′ RACE cloning of the TAL cDNA and the gene was expressed in the yeast Saccharomyces cerevisiae and in the bacterium Escherichia coli.

  • Phenol-induced proteins of Thauera aromatica
    Publication number: 20020042118
    Abstract: This invention pertains to genes coding for phenol-induced proteins Five phenol-induced proteins isolated from Thauera aromatica. Three dominant phenol-induced proteins called F1, F2, and F3 respecitively were purified and sequenced to obtain the enzyme(s) that catalyze the 14CO2:4-hydroxybenzoate isotope exchange reaction and the carboxylation of phenylphosphate. The N-terminal amino acid sequences of these proteins as well as the N-terminus of the phenol-induced proteins (F4 and F5) were also determined.
