Stabilized alpha-amylase variants and use of the same

An alpha-amylase variant, wherein said variant has alpha-amylase activity and comprises an amino acid sequence that has at least 89% sequence identity to the amino acid sequence of SEQ ID NO:

• 1, wherein said variant comprises an amino acid motif selected from the group consisting of FRCK (SEQ ID NO:
• 11), FRYK (SEQ ID NO:
• 12), FSIK (SEQ ID NO:
• 13), FSLK (SEQ ID NO:
• 14), FRLK (SEQ ID NO:
• 15), FSQK (SEQ ID NO:
• 16) and FSSK (SEQ ID NO:
• 17) at the positions corresponding to amino acids 179 to 182 of SEQ ID NO:
• 2;
• and wherein said variant has improved stability in a detergent compared to an alpha-amylase comprising the amino acid sequence of SEQ ID NO:
• 2 with the amino acid motif FTGK (SEQ ID NO:
• 6) at the positions corresponding to amino acids 179 to 182 of SEQ ID NO:
• 2, wherein stability is determined by a PHADEBAS amylase assay.
