Abstract
A mutated alkaline cellulase derived from a cellulase having the amino acid sequence represented by SEQ ID NO: 1 or one having a homology of at least 90% therewith by deleting one or more amino acid residues from the 343- to 377-positions in SEQ ID NO: 1 or a region corresponding thereto and then inserting a peptide having from 2 to 15 amino acid residues into the deletion site; and a gene encoding the same. The above alkaline cellulase has an optimum pH value close to the pH value of laundry water and, therefore, is useful as an enzyme for detergents.
