  • Patent number: 8865449
    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.

  • Patent number: 8535927
    Abstract: The present invention provides novel serine proteases, novel genetic material encoding these enzymes, and proteolytic proteins obtained from Micrococcineae spp., including but not limited to Cellulomonas spp. and variant proteins developed therefrom. In particular, the present invention provides protease compositions obtained from a Cellulomonas spp, DNA encoding the protease, vectors comprising the DNA encoding the protease, host cells transformed with the vector DNA, and an enzyme 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 protease(s) obtained from a Micrococcineae spp., including but not limited to Cellulomonas spp. In alternative embodiments, the present invention provides mutant (i.e., variant) proteases derived from the wild-type proteases described herein. These mutant proteases also find use in numerous applications.

  • Patent number: 8507244
    Abstract: Variants of Bacillus sp. TS-23 strain alpha-amylases exhibit improved enzymatic performance, including increased thermostability, reduced calcium dependence, increased washing/cleaning performance, and baking ability. Compositions comprising these variants are useful in methods of starch processing, starch liquefaction, fermatation, starch saccharification, cleaning, laundrying, textile desizing, baking, and biofilm removal.
