  • Protease muteins and their use in detergents
    Patent number: 6271012
    Abstract: New proteolytic enzymes are provided exhibiting improved properties for application in detergents, especially laundry detergents. These enzymes are obtained by expression of a gene encoding a proteolytic enzyme having an amino acid sequence which differs at least in one amino acid from the wild type enzyme. Preferred enzymes are certain mutants derived from the serine protease of Bacillus nov. spec. PB92.
    Type: Grant
    Filed: June 29, 1994
    Date of Patent: August 7, 2001
    Assignee: Genencor International, Inc.
    Inventors: Christian A. G. Van Eekelen, Leonardus J. S. M. Mulleners, Johannes C. Van Der Laan, Onno Misset, Roelck A. Cuperus, Johan H. A. Lensink
