Abstract
Certain variants of Lipolase (wild-type Humicolalanuginosa lipase) have a particularly good first-wash performance in a detergent solution. The variants should comprise one or more substitutions with positive amino acids near the N-terminal in the three-dimensional structure. The variants should further comprise a peptide addition at the C-terminal and/or should meet certain limitations on electrically charged amino acids at positions 90-101 and 210.
