| abstract |
the present invention relates to polypeptides that have cellulase activity, in particular variants derived from the 20k-cellulase enzyme. the invention describes several positions of amino acid residues important for the properties of the cellulase enzyme and thus for its stability and / or performance. the new variants have improved stability compared to precursor cellulase. in particular, the new variants perform well in an anti-darkening application and excellent stability in the presence of a protease in various detergent compositions, even in long-term experiments. |
