Patent ID: 7534594

Claim:
An isolated polynucleotide encoding a polypeptide having the property of enhancing cellulolytic activity of a cellulolytic polypeptide, selected from the group consisting of: (a) a polynucleotide encoding a polypeptide having the property of enhancing cellulolytic activity of a cellulolytic polypeptide and comprising an amino acid sequence having at least 95% identity to the mature polypeptide of SEQ ID NO: 2; (b) a polynucleotide encoding a polypeptide having the property of enhancing cellulolytic activity of a cellulolytic polypeptide, wherein the polynucleotide hybridizes under high stringency conditions with (i) the nucleic acid of SEQ ID NO: 1, or (ii) a full length complement strand of (i), wherein high stringency conditions are defined as prehybridization and hybridization at 42° C. in 5×SSPE, 0.3% SDS, 200 ug/ml sheared and denatured salmon sperm DNA, and 50% formamide and a wash three times each for 15 minutes using 2×SSC, 0.2% SDS at 65° C.; and (c) a polynucleotide encoding a polypeptide having the property of enhancing cellulolytic activity of a cellulolytic polypeptide, wherein the polynucleotide comprises a nucleotide sequence having at least 95% identity to the nucleic acid sequence of SEQ ID NO: 1.
