Kyozo Ogura 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).

  • Patent number: 6174715
    Abstract: The present invention provides a polypeptide selected from a polypeptide of subunit (A) or a polypeptide of subunit (B) of a prenyl diphosphate synthetase; a DNA coding for the polypeptide; a recombinant vector comprising the DNA; a transformant transformed with the vector; and a method for preparing an active type prenyl diphosphate synthetase. Also disclosed is a method for preparing an active type enzyme on which a specific property has been conferred, comprising mixing polypeptides of the two subunits of a heterodimeric enzyme, the polypeptides being derived from different organisms and one of the polypeptides having the specific property.
    Type: Grant

  • Patent number: 5786192
    Abstract: A DNA sequence that encodes a stable farnesyl pyrophosphate synthetase and the use thereof are provided. DNA sequence that encodes a farnesyl pyrophosphate synthetase originating from Bacillus stearothermophilus is provided. By selecting Bacillus stearothermophilus as the gene origin of the synthetase, a production system for the synthetase, a production system for the synthetase particularly having thermal stability, can be constructed.
