    摘要： The present invention relates to a method for improving the properties of a cellulolytic enzyme by amino acid substitution, deletion or insertion, the method comprising the steps of: a. constructing a multiple alignment of at least two amino acid sequences known to have three-dimensional structures similar to endoglucanase V (EGV) from Humicola insolens known from Protein Data Bank entry 4ENG; b. constructing a homology-built three-dimensional structure of the cellulolytic enzyme based on the structure of the EGV; c. identifying amino acid residue positions present in a distance from the substrate binding cleft of not more than 5 Å; d. identifying surface-exposed amino acid residues of the enzyme; e. identifying all charged or potentially charged amino acid residue positions of the enzyme; f. choosing one or more positions wherein the amino acid residue is to be substituted, deleted or where an insertion is to be provided; and g. carrying out the substitution, deletion or insertion by using conventional protein engineering techniques. Also described are cellulase variants obtained by this method.

    摘要： The present invention relates to enzymes produced by mutating the genes for a number of subtilases and expressing the mutated genes in suitable hosts are presented. The enzymes exhibit improved stability and/or improved wash performance in any detergent in comparison to their wild type parent enzymes. The enzymes are well-suited for use in any detergent and for some in especially liquid or solid shaped detergent compositions.
