Joong M. Cho 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).

  • Expression systems for making single-chain monellin analogs
    Patent number: 5487983
    Abstract: Single-chain analogs of the naturally occurring two-chain peptide monellin retain the sweetening properties of the natural protein and are stable under conditions which would otherwise destabilize the native peptide. A covalent linkage joins peptides corresponding to portions of the A and B chains of the naturally occurring protein.
    Type: Grant
    Filed: November 2, 1993
    Date of Patent: January 30, 1996
    Assignees: The Regents of the University of California, Lucky, Ltd.
    Inventors: Sung-Hou Kim, Joong M. Cho

  • Method for production of bovine growth hormone using a synthetic gene
    Patent number: 5366876
    Abstract: Plasmids for the high-level expression of bovine growth hormone in yeast and in E. coli are described, as are processes for the production of bovine growth hormone which utilize host cells transformed with the expression vectors.
    Type: Grant

  • Method for the production of salmon growth hormone using a synthetic gene
    Patent number: 5270180
    Abstract: High protein content feed or hormonal steroids have been added to fish feed in order to elevate the efficiency of the feed. However, the steroids remain in the fish and may be detrimental to those who eat the fish. The invention relates to a method for the production of salmon growth hormone, which enhances the efficiency of the feed without the above side effects, using a synthetic gene in yeast or E. coli. It has been found that salmon growth hormone may be produced economically and in bulk in yeast or E. coli by gene manipulation technology.

  • Single-chain monellin analog as a low calorie protein sweetner
    Patent number: 5264558
    Abstract: Single-chain analogs of the naturally occurring two-chain peptide monellin retain the sweetening properties of the natural protein and are stable under conditions which would otherwise destabilize the native peptide. A covalent linkage joins peptides corresponding to portions of the A and B chains of the naturally occurring protein.
    Type: Grant

    Inventors: Sung-Hou Kim, Joong M. Cho
  • Constructs for expression of monellin in plant cells
    Patent number: 5234834
    Abstract: Edible fruit, seed and vegetables of transgenic plants modified to produce a sweetening protein such as monellin or thaumatin are useful in preparing food compositions which have enhanced sweetness improved flavor. Expression systems for the genes encoding sweetening proteins compatible with plant systems and designed to enhance the production of these proteins in the edible portions of plants, and methods for producing sweetened fruit, seeds and vegetables are described.
