ALPHA-AMYLASE VARIANTS |
| 摘要 |
A variant polypeptide having alpha-amylase activity, wherein the variant has an amino acid sequence which, when aligned with the alpha-amylase comprising the sequence set out in SEQ ID NO: 2, comprises at least one substitution of an amino acid residue corresponding to any of amino acids 4, 6, 13, 14, 15, 16, 20, 45, 47, 51, 54, 61, 68, 69, 70, 71, 72, 73, 74, 75, 77, 78, 80, 82, 87, 88, 94, 95, 100, 103, 104, 117, 124, 125, 126, 128, 130, 133, 134, 136, 143, 144, 146, 168, 174, 177, 178, 183, 186, 188, 189, 190, 194, 195, 199, 200, 201, 204, 207, 210, 214, 217, 219, 222, 225, 227, 233, 234, 235, 236, 240, 251, 252, 254, 258, 259, 260, 261, 262, 263, 264, 266, 267, 269, 271, 273, 281, 282, 283, 284, 286, 288, 299, 322, 323, 325, 327, 328, 331, 334, 350, 356, 358, 367, 370, 371, 374, 377, 378, 388, 391, 414, 421, 422, 445, 450, 467, 488, 505, 536, 548, 583, 588, 603, 637, 648, 651, 652, 660, 676, 677,;said positions being defined with reference to SEQ ID NO: 2 and wherein the variant has one or more altered properties as compared with a reference polypeptide having alpha-amylase activity. Such a variant polypeptide may be used in the preparation of a baked product. |
