Abstract
The present invention relates to variants of a Family 7 cellulase comprising one or more mutations of the amino acid sequence of the cellulase in which each mutation is independently a substitution of an amino acid residue with another amino acid or an insertion of at least one amino acid residues, wherein the variant has a modified H-bonding potential and hydrophobic interaction relative to the cellulase. The present invention also relates to the use of the cellulase variants in detergent compositions, especially for soil removal or color clarification or preventing backstaining; in fabric softeners; for bio-polishing of textiles; for drainage improvement of paper pulp; for deinking of old paper; for plant degradation.
