Abstract

The present invention provides phosphatases with improved phytase activity. The invention provides proteolytic fragments of phosphatase having improved phytase activity. A recombinant gene encoding a phosphatase fragment having improved phytase activity is also provided. The invention also includes a method of increasing the phytase activity of phosphatase by treating the phosphatase with a protease. In addition, the invention provides a phosphatase, AppA2, having improved properties.
