Abstract

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