  • Patent number: 8785365
    Abstract: The present invention relates to ?-amylase variants that are stabilized to dimerization and/or multimerization, in particular at elevated temperatures or high pH, by point mutagenesis of positively polarized or charged or neutral surface amino acids to give more negatively polarized or charged amino acids. The invention further relates to methods of increasing the stability of an ?-amylase to dimerization and/or multimerization brought about by electrostatic interactions whereby at least one amino acid residue on the surface of the starting molecule, which makes a neutral or positively polar or charged contribution to the electrostatic potential of said molecule, is replaced with a more negatively polar or negatively charged amino acid residue. The ?-amylase variants obtained thereby exhibit better stability to influences of the solvent, increased processivity, and are suited for numerous industrial areas of use, in particular as active ingredients in detergents and cleansers.

    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.

  • Patent number: 8546099
    Abstract: The inventors have modified the amino acid sequence of a maltogenic alpha-amylase to obtain variants with improved properties, based on the three-dimensional structure of the maltogenic alpha-amylase Novamyl. The variants have altered physicochemical properties, e.g. an altered pH optimum, improved thermostability, increased specific activity, an altered cleavage pattern or an increased ability to reduce retrogradation of starch or staling of bread.

  • Patent number: 8545907
    Abstract: The present disclosure relates to an enzyme blend comprising a low pH, thermostable alpha-amylase and a Bacillus licheniformis alpha-amylase. The blend can include at least about 1.0 Liquefon Unit (LU) of the B. licheniformis alpha-amylase for every 5.0 Modified Wohlgemuth Unit (MWU) of the low pH, thermostable alpha-amylase. The enzyme blend described is suitable for starch liquefaction and saccharification, ethanol production, and/or sweetener production, among other things. Also provided herein is a method of processing a starch by liquefying the starch with the low pH, thermostable alpha-amylase and the Bacillus licheniformis alpha-amylase, simultaneously or sequentially.
