Patents by Inventor Jin Konishi

Jin Konishi 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 encoding desulfurization enzymes
    Patent number: 6607903
    Abstract: This invention provides novel genes encoding enzymes which decompose difficult-to-decompose thiophene compounds. By using these genes, sulfur atoms can be released from the thiophene compounds in fossil fuel such as petroleum, and the diffusion of sulfur into the environment caused by the combustion of the fossil fuel can be prevented.
    Type: Grant
    Filed: April 10, 2002
    Date of Patent: August 19, 2003
    Assignee: Petroleum Energy Center
    Inventors: Yoshitaka Ishii, Jin Konishi, Kazuaki Hirasawa, Hideki Okada, Masanori Suzuki

  • High-temperature desulfurization by microorganisms
    Patent number: 6130081
    Abstract: The present invention relates to a method of degrading organic sulfur compounds, in which organic sulfur compounds are decomposed by a microorganism belonging to the genus Paenibacillus and having the ability to decompose organic sulfur compounds. Heterocyclic sulfur compounds can be decomposed by specifically cleaving their C--S bonds under high-temperature conditions.

  • Methods and compositions for promoting protein folding
    Patent number: 5561221
    Abstract: Disclosed are 1) compositions comprising isolated monomeric subunits of chaperonin-60 or truncated fragments thereof that promote the folding of a polypeptide chain in vitro, 2) monomeric subunits of chaperonin-60 or truncated fragments thereof, immobilized on a solid surface, that promote also the folding of a polypeptide chain in vitro, 3) methods for preparing and/or immobilizing the monomeric subunits of chaperonin-60 or truncated fragments thereof, and 4) methods for folding polypeptide chains, specifically polypeptide chains expressed in a heterologous expression system, in vitro using the monomeric subunits of chaperonin-60 or truncated fragments thereof.
