More Information
Summary:A phytase comprising one or more substitutions corresponding to positions A122, D125, T167, F197, T209, A211, K240, A242, S281, Q289, A294 and N303 of SEQ ID NO:1 in a phytase derived from Butiauxella sp strain P1-29. The phytase enzymes described herein have increased thermal stability, higher proteolytic activity, or higher specific activity as compared to Butiauxella sp strain P1-29 or the BP-11 phytase. La présente invention concerne des variants des enzymes que sont les phytases, dotés de propriétés modifiées.
