Abstract

The present invention relates to polypeptides having cellulase activity, in particular to variants derived from the 20K-cellulase enzyme. The invention discloses a number of amino acid residue positions important for the properties of the cellulase enzyme and thereby for the stability and/or performance thereof. The novel variants have improved stability compared to the parental cellulase. In particular, the novel variants have good performance in an antigreying application and excellent stability in the presence of a protease in several detergent compositions even in long-term experiments.
