摘要: The present invention relates to variants of a parent glucoamylase having altered properties (e.g., improved thermostability and/or specific activity). In particular, the present invention provides compositions comprising the variant glucoamylases, including starch hydrolyzing compositions, animal feed compositions and cleaning compositions. The invention also relates to DNA constructs encoding the variants and methods of producing the glucoamylase variants in host cells.
