    摘要： A variant of a parent .alpha.-amylase enzyme having an improved washing and/or dishwashing performance as compared to the parent enzyme, wherein one or more amino acid residues of the parent enzyme have been replaced by a different amino acid residue and/or wherein one or more amino acid residues of the parent .alpha.-amylase have been deleted and/or wherein one or more amino acid residues have been added to the parent .alpha.-amylase enzyme, provided that the variant is different from one in which the methionine residue in position 197 of a parent B. licheniformis .alpha.-amylase has been replaced by alanine or threonine, as the only modification being made. The variant may be used for washing and dishwashing.

    摘要翻译： 与母体酶相比，具有改善的洗涤和/或餐具洗涤性能的母体α-淀粉酶的变体，其中母体酶的一个或多个氨基酸残基已被不同的氨基酸残基替代和/或其中一个 或更多的母体α-淀粉酶的氨基酸残基已经缺失和/或其中一个或多个氨基酸残基已加入到母体α-淀粉酶中，条件是该变体不同于其中位置上的甲硫氨酸残基的变体 作为唯一的修改，母本地衣芽孢杆菌α-淀粉酶的197已被丙氨酸或苏氨酸代替。 该变体可用于洗涤和洗碗。
