  • Patent number: 6936444
    Abstract: The patent application describes a process for the enzymatic chiral synthesis of L-phosphinothricin by transamination from its corresponding keto acid PPO with aspartate as amino donor. It is possible by a suitable reaction procedure to achieve a quantitative conversion on use of approximately equimolar amounts of amino donor and acceptor with complete consumption of the donor amino acid aspartate. The use of thermally stable transaminases makes a higher reaction rate and correspondingly large space/time yields possible.

  • Patent number: 6262339
    Abstract: The invention is directed to a process for the generation of male sterility in plants comprising the steps of (a) transforming a plant cell with DNA sequences that selectively inhibit the expression of essential metabolic compounds and (b) regenerating plants from said plant cells. Cells impaired in the biosynthesis of basic metabolic compounds undergo starvation and eventually die. Such pathways include amino acid biosynthesis, nucleic acid biosynthesis and other biosynthetic pathways such as citric acid cycle, pentose phosphate pathway, fatty acid metabolism, vitamin biosynthesis that will render the cell inactive due to nutrient depletion, if one or more enzymes or proteins involved in this pathway would become inactive by using inhibitory DNA constructs.
