    • A cellulase variant of a parent cellulase, e.g. a cellulase classified in family 45 such as a Humicola insolens 43 kD endoglucanase, comprising a cellulose binding domain (CBD), a catalytically active domain (CAD) and a region linking the cellulose binding domain and catalytically active domain (the linking region), wherein one more amino acid residues of the CBD, CAD or linking region is deleted or substituted by one or more amino acid residues and/or one or more amino acids are added to the linking region and/or another CBD is added at the opposite end of the catalytically active domain, has improved properties as regards e.g. alkaline activity, compatibility with detergent composition ingredients, particulate soil removal, colour clarification, defuzzing, depilling, harshness reduction, and sensitivity to anionic surfactants and peroxidase bleaching systems and is useful e.g. in detergent compositions, for textile treatment, in paper pulp processing, for animal feed and for stone washing of jeans.

    • The invention relates to novel Achromobacter lyticus protease I variants wherein one or more of the lysine residues in positions 30, 49, 106, 155 and 203 have been replaced by another amino acid residue which can be encoded by nucleic acid constructs, or wherein one or more of the lysine residues in the above-mentioned positions or other amino acid residues introduced into the above-mentioned positions have been chemically modified. The invention furthermore relates to nucleic acid constructs encoding said protease variants, and vectors and host cells comprising said constructs. The protease variants are useful for cleaving Lys-X peptide bonds in polypeptides, such as preproinsulins.
