The invention relates to phytases, polynucleotides encoding them, uses of the polynucleotides and polypeptides of the invention, as well as the production and isolation of such polynucleotides and polypeptides. In particular, the invention relates to polypeptides having phytase activity under high temperature conditions, and phytases that remain active after exposure to high temperatures. The invention additionally relates to phytases that have increased lability in the stomach. The phytases of the invention can be used in food products to enhance the nutritional value of phytate-rich ingredients. The phytases according to the invention can be prepared in the form of food or feed, or food or feed additives, for example, that phytases promote the breakdown of phytate. |
