  • Yeast transformant producing recombinant human parathyroid hormone and method for producing the hormone
    Patent number: 7244591
    Abstract: Novel Saccharomyces Cerevisiae mutant strains are provided for producing human parathyroid hormone. The novel strains acre genetically disrupted in at least one of the genes encoding the yapsin family of proteases Yapsin 1, Yapsin 2 and Yapsin 3 and harbor a human parathyroid hormone gene in their genomes. Culturing the novel strains results in the secretion of intact hPTH into culture media at high yield.
    Type: Grant
    Filed: August 27, 2001
    Date of Patent: July 17, 2007
    Assignee: Dong Kook Pharmaceutical Co., Ltd.
    Inventors: Sang Ki Rhee, Hyun Ah Kana, Bong Hyun Chung, Su Min Ko
