Estimating the term…
The invention relates to a mutant α-amylase having an amino acid sequence obtained by making deletion or replacement by another arbitrary amino acid residue of at least a methionine residue at the 202-position or a position homologous thereto among amino acid residues set forth in SEQ ID NO:1, which constitute a liquefying alkaline α-amylase, a gene thereof, and a detergent composition comprising the mutant α-amylase. The mutant α-amylase has the optimum pH in an alkaline range, an excellent α-amylase activity, and high and lasting resistance to oxidizing agents, and is hence particularly useful as a component of detergent compositions containing a bleaching agent and an oxidizing agent.
A mutant α-amylase obtained by introducing a deletion or a replacement of a methionine residue at the 202-position in the amino acid sequence set forth in SEQ ID NO:1, or by introducing a deletion or a replacement of a methionine residue at a position homologous to the 202-position of SEQ ID NO:1 in an amino acid sequence having at least 95.2% homology to SEQ ID NO:1,
