Described are compositions and methods relating to variant alpha-amylases having altered biochemical properties and advantageous performance characteristics as compared to a reference alpha-amylase. The variants are suitable for use in various industrial applications such as starch conversion, ethanol production, laundry, dishwashing, pulp and paper production, textile desizing, and/or sweetener production.
