  • Publication number: 20110033882
    Abstract: Variants of B. licheniformis alpha-amylase advantageously exhibit improved enzymatic performance. Suitable variants include those with an altered charge distribution on the surface of the enzyme or with altered active site residues. Structural modeling can inform the choice of amino acid modifications so that modified amino acids correspond to residues found in more active alpha amylases, for example. Compositions comprising the variants are useful in methods of cleaning surfaces, laundering textiles, desizing, treating starch, e.g., liquefaction and saccharification, and hydrolyzing biofilms off various substrates.

  • Publication number: 20110027252
    Abstract: Variants of Bacillus sp. no. 707 alpha amylase are provided that are produced more efficiently and thus more economically. Higher fermentation yields are achieved through introducing amino acid variations that promote solubility of the variant in a fermentation broth. Increased solubility allows more enzyme to remain in solution after expression in a host cell. This in turn increases the efficiency with which the expressed variant enzyme can be recovered from the fermentation broth.

  • Patent number: 6939703
    Abstract: The present invention relates to novel amylolytic enzymes having improved characteristics for the use in starch degradation, in textile or paper desizing and in household detergent compositions. The disclosed ?-amylases show surprisingly improved properties with respect to the activity level and the combination of thermostability and a higher activity level. These improved properties make them more suitable for the use under more acidic or more alkaline conditions. The improved properties allow also the reduction of the Calcium concentration under application conditions without a loss of performance of the enzyme.
