Patent ID: 7432098

Claim:
An isolated, synthetic or recombinant polypeptide having a phytase activity, wherein the polypeptide comprises an amino acid sequence selected from the group consisting of: (a) an amino acid sequence having at least 99% sequence identity to SEQ ID NO: 2; (b) an amino acid sequence which is a variant of SEQ ID NO: 4, wherein said 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; (c) the amino acid sequence of (a) or (b) lacking a signal (leader) sequence; (d) the amino acid sequence of (a), (b) or (c) further comprising a heterologous sequence; or (e) the amino acid sequence of (a), (b), or (c) further comprising a heterologous sequence encoding a signal (leader) peptide.
