Patent number: 8129511Abstract: This invention relates to nucleic acids encoding amylase polypeptides, the encoded polypeptides and uses thereof. The amylases of the present invention have been engineered to have more beneficial qualities. Specifically, the amylases of the current invention show an altered exo-specificity and/or thermostability. Some embodiments of the invention relate to said polypeptides and nucleic acids and their uses as non-maltogenic exoamylases in producing food products.Type: GrantFiled: February 8, 2011Date of Patent: March 6, 2012Assignee: Danisco A/SInventors: Karsten Matthias Kragh, Bo Spange Sørensen, Casper Tune Berg, Kirsten Bojsen, Patrick M.
