The invention provides polypeptides having phytase activity and polynucleotide sequences encoding the phytase. The gene expresses the phytase in an amount of at least 7 g/l to 40 g/L. These phytase enzymes have higher specific activity, retain activity at low pH, retain activity at high temperatures, have increased phosphorus equivalent, increased phosphorus bioavailability, and increased phosphorus hydrolysis. These phytase enzymes can be used in a variety of industries including food, feed, ethanol production, pharmaceuticals and cleaning. |
