    摘要: The invention relates to a mutant &agr;-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 &agr;-amylase, a gene thereof, and a detergent composition comprising the mutant &agr;-amylase. The mutant &agr;-amylase has the optimum pH in an alkaline range, an excellent &agr;-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.
