  • Patent number: 9388399
    Abstract: Genes SWA2 and GAM1 from the yeast, Schwanniomyces occidentalis, encoding ?-amylase and glucoamylase, respectively, were cloned and expressed in H. polymorpha. The expression was achieved by integration of the SWA2 and GAM1 genes into the chromosome of H. polymorpha under operably linked to a strong constitutive promoter of the H. polymorpha-glyceraldehyde-3-phosphate dehydrogenase gene (HpGAP. Resulting transformants acquired the ability to grow on a minimal medium containing soluble starch as a sole carbon source and can produce Ethanol at high-temperature fermentation from starch up to 10 g/L. A XYN2 gene encoding endoxylanase was obtained from the fungus Trichoderma resee, and a xlnD gene coding for ?-xylosidase was obtained from the fungus Aspergillus niger. Co-expression of these genes was also achieved by integration into the H. polymorpha chromosome under control of the HpGAP promoter.

  • Publication number: 20150017701
    Abstract: Hybrid alpha-amylases are provided that share a conserved 3D structure in whole or in part with a wild-type Termamyl-like ?-amylase, e.g., a Bacillus amylase. In the hybrid, an N-terminal portion of a Termamyl-like ?-amylase is replaced with sequences from an archae ?-amylase. The sequence similarity between the two amylase sequences may be less than 60%. Conserving the wild-type 3D structure in the hybrid facilitates obtaining enzymatically active amylases. In one embodiment, one or both amylase sequences contribute residues to the B domain, resulting in particularly advantageous properties. For instance, replacement of the Ca2+ binding site in the B domain of the Termamyl-like ?-amylase with a B domain sequence of an archae ?-amylase that does not bind Ca2+ can produce a hybrid that is fully active in the absence of Ca2+.

  • Publication number: 20140377407
    Abstract: This invention relates to a novel alpha-amylase, a process for its preparation and the use of the amylase. The invention relates to a newly identified polynucleotide sequence from Alicyclobacillus pohliae comprising a gene that encodes the novel alpha-amylase enzyme. The invention features the full length coding sequence of the novel gene as well as the amino acid sequence of the full-length functional protein of the gene. The invention also relates to methods of using these proteins in industrial processes, for example in food industry, such as the baking industry. Also included in the invention are cells transformed with a polynucleotide according to the invention suitable for producing these proteins and cells.

  • Patent number: 8916369
    Abstract: A maltogenic a-amylase from Trichoderma reesei (TrAA) and variants thereof are useful in the production of high-maltose syrups from liquefied starch. Particularly high maltose concentrations are achieved when TrAA is used in the presence of a pullulanase. Expression hosts and encoding nucleic acids useful for producing TrAA and its variants also are provided.
