Misao Sunagawa 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).

  • Genes of cell wall-degrading enzymes derived from aspergillus, and method for the production the enzymes
    Patent number: 7285407
    Abstract: The purpose of the present invention is to isolate a gene encoding novel exo-, or endo-?-1,3-glucanase, to obtain a microorganism having an enhanced expression of said gene and to degrade ?-1,3-glucan to its low molecular weight form by means of said enzymes. The present invention relates to a gene or DNA encoding novel enzymes having ?-1,3-glucanase activity (exo-, or endo-?-1,3-glucanase), a recombinant expression vector comprising them, a microorganism having the recombinant expression vector, the novel enzymes having ?-1,3-glucanase activity, and a method for the production of said enzymes.
