Opening claim text (preview).
The invention claimed is: 1 . A polypeptide comprising a variant amino acid sequence of SEQ ID NO: 1, wherein the polypeptide has alpha-amylase activity, has at least 90% sequence identity to the amino acid sequence set forth in SEQ ID NO: 1, comprises a M116A, or M116V at the position corresponding to position 116 wherein numbering is according to the amino acid sequence set forth in SEQ ID NO: 2, and exhibits an enhanced wash performance compared to the polypeptide of SEQ ID NO: 1. 2 . A polypeptide according to claim 1 wherein the enhanced wash performance is assessed using an Automatic Mechanical Stress Assay (AMSA) assay. 3 . A polypeptide according to claim 1 wherein the enhanced wash performance is exhibited during high temperature washes. 4 . A polypeptide according to claim 3 , wherein said high temperature is at least 40° C. 5 . A polypeptide according to claim 2 , wherein said polypeptide exhibits an enhanced wash performance in one or more of the conditions selected from the group consisting of: (a) Model ADW (Automatic Dish Wash) detergent with bleach at 40° C. and a wash cycle of 10 min; (b) Model ADW detergent without bleach at 40° C. and a wash cycle of 10 min; (c) Model ADW detergent with bleach at 50° C. and a wash cycle of 20 min; and (d) Model ADW detergent without bleach at 50° C. and a wash cycle of 20 min; wherein said model ADW detergent comprises trisodium salt of methylglycinediacetic acid, sodium citrate, sodium carbonate, sodium silicate, sodium sulphate, polyphosphate and silicate scale inhibitor. 6 . A polypeptide according to claim 1 further comprising a mutation at one or more positions corresponding to positions 10, 25, 30, 37, 40, 48, 51, 54, 64, 81, 86, 93, 98, 105, 108, 109, 113, 118, 121, 130, 135, 138, 142, 167, 174, 175, 178, 182, 186, 187, 189, 195, 198, 202, 203, 206, 208, 210, 214, 218, 235, 238, 242, 243, 246, 247, 250, 255, 257, 259, 260, 261, 265, 267, 269, 270, 274, 275, 276, 281, 295, 298, 299, 311, 319, 320, 334, 339, 360, 365, 366, 383, 384, 385, 394, 398, 402, 404, 416, 434, 460, 469, 474, and 482, wherein numbering is according to the amino acid sequence set forth in SEQ ID NO: 2. 7 .
