Patents by Inventor Young-Yell Yang

Young-Yell Yang 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).

  • Adenosylmethionine synthetase from , gene sequences coding the same and method for mass production of secondary metabolites including antibiotics thereof
    Patent number: 7666631
    Abstract: Disclosed is an isolated nucleotide sequence encoding an enzyme catalyzing biosynthesis of SAM (SAM-s) and its amino acid sequence. Also, the present invention provides a method for mass production of a useful secondary metabolite including antibiotics using the isolated nucleotide sequence and SAM, where SAM acts as a methyl group donor.
    Type: Grant

  • Methods for producing transgenic plants with enhanced resistance and decreased uptake of heavy metals
    Patent number: 7173163
    Abstract: The present invention relates to a method of producing transformants with enhanced resistance and decreased uptake of heavy metals, and a plant transformed with a P type ATPase ZntA gene that pumps out heavy metals from the cells. The transformants show better growth than wild type in environment contaminated with heavy metals and have lower heavy metal contents than wild type plants. Therefore, this method of transforming plants with ZntA or biologically active ZntA—like heavy metal pumping ATPases can be useful for developing plants for phytoremediation and also for a safe crop that has resistance to heavy metals and low heavy metal contents.
