Abstract:
1. A mutated alkaline cellulase which is obtained by deleting, from a cellulase having the amino acid sequence of SEQ ID NO: 2 or a homologous amino acid sequence exhibiting at least 95% sequence homology therewith, a peptide consisting of one or more amino acid residues chosen from the 357 th to 362 nd positions in SEQ ID NO: 2 or from corresponding positions of said homologous amino acid sequence and replacing the peptide with an insertion peptide selected from the group consisting of: asparagine-threonine-alanine-valine-glycine-isoleucine, alanine-serine-methionine-leucine-phenylalanine-glutamic acid, cysteine-leucine-glycine-histidine-serine, tyrosine-glutamine-lysine-alanine-alanine, aspartic acid-methionine-isoleucine-valine, isoleucine-threonine-proline-lysine, glycine-leucine-cysteine, serine-valine-phenylalanine, and a peptide containing alanine residues at both ends thereof and having 3 to 6 residues, wherein said mutated alkaline cellulase has alkaline cellulase activity.
