Abstract
The present invention relates to glucoamylase variants. In particular, the invention relates to variants in the starch binding domain (SBD) of a glucoamylase. The invention also relates to variants having altered properties (e.g., improved thermostability and/or increased specific activity) as compared to a corresponding parent glucoamylase. The present invention also provides enzyme compositions comprising the variant glucoamylases; DNA constructs comprising polynucleotides encoding the variants; and methods of producing the glucoamylase variants in host cells.
