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.
