  • Patent number: 5877139
    Abstract: There is provided an enzymatic detergent composition comprising one or more surfactants and an endoglucanase which is not a Family 7 cellulase, which contains no cellulose binding domain and wherein the catalytic domain contains at least two disulphide bridges. Preferably, the endoglucanase is producible from Thermomonospora fusca, or mutants or variants thereof.

  • Patent number: 5858757
    Abstract: The invention relates to stabilized subtilisin proteases wherein one or more prolines is substituted for a native amino acid at stabilizing positions defined both by the range of the dihedral angles in the primary structure present at the substitution site and by selected characteristics of the protease secondary structure in the vicinity of the substitution site, to nucleotide sequences that encode the stabilized proteases, and to host organisms that contain the nucleotide sequences encoding the stabilized proteases.
