Patent ID: 7851193

Claim:
An isolated polypeptide having xylanase activity, selected from the group consisting of: (a) a polypeptide comprising an amino acid sequence having at least 95% sequence identity to the mature polypeptide of SEQ ID NO: 2; (b) a polypeptide encoded by a polynucleotide that hybridizes under high stringency conditions with (i) the mature polypeptide coding sequence of SEQ ID NO: 1, (ii) the genomic DNA sequence comprising the mature polypeptide coding sequence of SEQ ID NO: 1, or (iii) a full-length complementary strand of (i) or (ii), wherein 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 for 12 to 24 hours, and washing three times each for 15 minutes using 2×SSC, 0.2% SDS preferably at 65° C.; and (c) a polypeptide encoded by a polynucleotide comprising a nucleotide sequence having at least 95% sequence identity to the mature polypeptide coding sequence of SEQ ID NO: 1.
