Abstract

The present invention relates to glucoamylase variants having an increase in specific activity and/or an increase in melting temperature measured by TSA of at least 0.5 degrees Celsius, and further wherein the variants have at least at least 85%, at least 90%, at least 95% identity, at least 96%, at least 97%, at least 98%, or at least 99%, but less than 100%, sequence identity to the amino acid sequence of SEQ ID NO: 3. The present invention also relates to polynucleotides encoding the variants; nucleic acid constructs, vectors, and host cells comprising the polynucleotides; and methods of using the variants.
