  • Genes encoding eglin C mutants
    Patent number: 5180667
    Abstract: DNA encoding novel eglin mutants that differ from the natural eglins B and C by the replacement of amino acids in the region of the active center (amino acid 45) by other amino acids are provided. The mutants, which are produced by recombinant genetic engineering, have valuable pharmacological properties.
    Type: Grant
    Filed: October 11, 1991
    Date of Patent: January 19, 1993
    Assignees: Ciba-Geigy Corporation, UCP Gen-Pharma, AG
    Inventors: Markus G. Grutter, Dirk Heinz, Manfred Liersch
  • Modified eglin proteins
    Patent number: 5079229
    Abstract: Novel elgin mutants that differ from the natural eglins B and C by the replacement of one, two or three amino acids in the region of the active center (amino acids 45 and 46, Leu-Asp) by other amino acids are provided. The mutants, which can be produced by recombinant genetic engineering, have valuable pharmacological properties.
