Abstract:
The present invention relates to variant glucoamylases wherein the variant has altered properties (e.g., improved thermostability and/or specific activity) compared to a corresponding parent glucoamylase. The present invention also relates to enzyme compositions comprising a variant glucoamylase (e.g., starch hydrolyzing compositions); DNA constructs comprising polynucleotides encoding the variants and methods of producing the variant glucoamylases in host cells.
