Patent ID: 8624082

Claim:
An isolated polypeptide having xylanase activity, selected from the group consisting of: (a) a polypeptide having at least 95% sequence identity to amino acids 28 to 255 of SEQ ID NO: 2; (b) a polypeptide encoded by a polynucleotide that hybridizes under at least very high stringency conditions with (i) nucleotides 82 to 851 of SEQ ID NO: 1, (ii) a cDNA sequence thereof, or (iii) the full-length complement of (i) or (ii), wherein very high stringency conditions are defined as prehybridization and hybridization at 42° C. in 5× SSPE, 0.3% SDS, 200 μg/ml sheared and denatured salmon sperm DNA, and 50% formamide and washing three times each for 15 minutes using 2× SSC, 0.2% SDS at 70° C.; (c) a polypeptide encoded by a polynucleotide having at least 99% sequence identity to nucleotides 82 to 851 of SEQ ID NO: 1, or the cDNA sequence thereof; and (d) an isolated fragment of the polypeptide of (a), (b), (c), or (d) that has xylanase activity.
