Patent ID: 8206962

Claim:
A non-naturally occurring phytase which has at least 80% identity to the sequence of amino acid residues 1-413 of SEQ ID NO:2 and which comprises at least one modification at a position selected from the group consisting of: 1, 8, 9, 12, 16, 18, 26, 32, 33, 35, 41, 45, 48, 49, 54, 63, 64, 66, 69, 72, 75, 76, 77, 78, 82, 83, 89, 92, 93, 95, 96, 98, 100, 101, 103, 109, 111, 112, 113, 115, 116, 117, 118, 119, 120, 121, 122, 123, 130, 131, 132, 137, 138, 139, 143, 144, 146, 148, 150, 151, 152, 160, 162, 163, 168, 172, 173, 175, 176, 178, 179, 181, 186, 187, 190, 192, 193, 199, 201, 206, 207, 208, 211, 217, 221, 228, 234, 239, 242, 245, 246, 247, 249, 251, 256, 259, 260, 261, 266, 285, 286, 289, 293, 294, 303, 304, 308, 310, 313, 320, 325, 331, 346, 348, 354, 355, 358, 363, 368, 369, 370, 382, 383, 394, 396, 401, and 403, wherein each modification is independently a substitution, deletion or insertion and each position corresponds to the position of the phytase with the sequence of amino acids 1-413 of SEQ ID NO:2, wherein the phytase is not the phytase with the sequence of amino acids 1-413 of SEQ ID NO:2.
