FIELD: biotechnology, biochemistry, enzymology. ^ SUBSTANCE: variant of the parent Termamil-like alpha-amylase comprises change in one or some positions of the parent alpha-amylase. Such changes represent insertions, deletions and substitutions of amino acids in amino acid sequence of this enzyme. Indicated variant retains activity of alpha-amylase and elicits alternated properties such as reduced capacity for substrate cleavage near the branching point and improved substrate specificity. Invention enhances effectiveness in using alpha-amylase in detergent compositions, in manufacturing ethanol, for treatment of fabrics or dressings. ^ EFFECT: valuable properties of enzyme. ^ 13 cl, 5 ex |
