Abstract
Alpha-amylases from(AmyE), variants thereof, nucleic acids encoding the same, and host cells comprising the nucleic acids are provided. Methods of using AmyE or variants thereof are disclosed, including liquefaction and/or saccharification of starch. Such methods may yield sugars useful for ethanol production or high fructose corn syrup production. In some cases, the amylases can be used at low pH, in the absence of calcium, and/or in the absence of a glucoamylase.
