Abstract
The invention relates to the use of mutated protease of the subtilisin type which carries at least one mutation in its amino acid sequence, leading to a reduced positive charge or an increased negative charge in the substrate binding region of the molecule, in liquid to gel-form laundry detergents. This protease shows increased stability above all in detergents such as these.
