  • Patent number: 7618801
    Abstract: Certain aspects of this disclosure relate to an isolated protease, and cleaning compositions containing the same. In some embodiments, the protease may comprise an amino acid sequence that is at least 80% identical to the wild type Streptomyces 1AG3 protease. Isolated nucleic acid encoding the subject protease, recombinant nucleic acid containing the same and host cells containing the recombinant nucleic acid are also provided.
    Type: Grant
    Filed: October 30, 2007
    Date of Patent: November 17, 2009
    Assignee: Danison US Inc.
    Inventors: Brian E. Jones, Marc Kolkman, Chris Leeflang

  • Publication number: 20080063774
    Abstract: The present invention provides novel Micrococcineae spp serine proteases having multiple substitutions. In particular, the present invention provides serine proteases having multiple substitutions, DNA encoding these proteases, vectors comprising the DNA encoding the proteases, host cells transformed with the vector DNA, and enzymes produced by the host cells. The present invention also provides cleaning compositions (e.g., detergent compositions), animal feed compositions, and textile and leather processing compositions comprising these serine protease variants. In particularly preferred embodiments, the present invention provides mutant (i.e., variant) proteases derived from the wild-type proteases described herein. These variant proteases also find use in numerous applications.

  • Publication number: 20060252155
    Abstract: The present invention provides methods and compositions for the construction and direct transformation of site-saturation libraries into Bacillus. This method avoids the need for the use of intermediate hosts, such as E. coli for the development of Bacillus strains suitable for the production of proteins.
