Patent ID: 7824895

Claim:
An isolated, synthetic or recombinant nucleic acid comprising: (a) a nucleic acid having at least 99% or 100% sequence identity to the nucleic acid of SEQ ID NO: 1, wherein said nucleic acid encodes a polypeptide having phytase activity; (b) a nucleic acid encoding a polypeptide having at least 99% or 100% sequence identity to the polypeptide of SEQ ID NO: 2, wherein the polypeptide has phytase activity; (c) a nucleic acid encoding a polypeptide having an amino acid sequence which is a variant of SEQ ID NO: 4, wherein the variant differs from SEQ ID NO: 4 solely by an amino acid substitution selected from the group consisting of W68E, Q84W, A95P, K97C, S168E, R181Y, N226C, Y277D, and any combination thereof, wherein the polypeptide has a phytase activity; or (d) the nucleic acid of any of (a) to (c), wherein the nucleic acid lacks a nucleic acid encoding a native signal sequence.
