Patent 7960160 was granted and assigned to Novozymes on June, 2011 by the United States Patent and Trademark Office.
The present invention relates to an isolated polypeptide having xylanase activity from Aspergillus fumigatus with a molecular weight of approximately 50 kDa by SDS-PAGE and homologous polypeptides thereof comprising an amino acid sequence having at least 95% identity with amino adds 20 to 397 of SEQ ID NO: 6; encoded by a polynucleotide comprising a nucleotide sequence having at least 95% identity with nucleotides 107 to 1415 of SEQ ID NO: 5: or encoded by a polynucleotide that hybridizes under high stringency conditions with (i) nucleotides 107 to 1415 of SEQ ID NO: 5, (ii) the cDNA sequence of (i), or (iii) a full-length complementary strand of (i) or (ii). The present invention also relates to a method for producing such polypeptides having xylanase activity comprising: (a) cultivating a wild-type Aspergillus fumigatus cell under conditions conducive for production of the polypeptide; and (b) recovering the polypeptide.
