Abstract
A modified Family 6 cellulase enzyme comprising a proline residue at position 413 is provided. Genetic constructs and genetically modified microbes comprising DNA sequences encoding the modified Family 6 cellulase are also provided. Family 6 cellulases of the invention display improved thermostability, thermophilicity, alkalophilicity, or a combination thereof, relative to the parent Family 6 cellulases. Such cellulases find use in a variety of applications in industry that require cellulase stability and activities at temperatures, pH values, or both, above that of the native enzyme.
