ISOLATED POLYPEPTIDE, ISOLATED POLYNUCLEOTIDE, NUCLEIC ACID CONSTRUCTION, RECOMBINANT EXPRESSION VECTOR, RECOMBINANT HOST STONE CELL, METHODS FOR PRODUCTION OF POLYPEPTIDE, FOR IMPROVED NUTRITIONAL PRODUCT VALUATION, PLANT OR PLANT CELL, TRANSGENIC, NON-HUMAN ANIMAL, OR PRODUCTS OR ELEMENTS OF THE SAME, USE OF AT LEAST ONE POLYPEPTIDE, ANIMAL FEED ADDITIVE, AND, ANIMAL FEED COMPOSITION.
The present invention relates to isolated polypeptides having phytase activity and isolated polynucleotides encoding the polypeptides. The polypeptides are related to a phytase derived from Hafnia alvei, the amino acid sequence of which is shown in the appended sequence listing as SEQ ID NO: 10. The invention also relates to nucleic acid constructs, vectors, and host cells comprising the polynucleotides as well as methods for producing and using the polypeptides, in particular within animal feed.
