Claim Text:
1. A nucleic acid construct comprising an isolated polynucleotide encoding a GH61 polypeptide having cellulolytic enhancing activity, wherein the polynucleotide is operably linked to control sequences that direct expression of the polynucleotide in a suitable host cell and wherein one or more of the control sequences are foreign to the polynucleotide, wherein the GH61 polypeptide having cellulolytic enhancing activity is selected from the group consisting of: (a) a GH61 polypeptide having at least 90% sequence identity to the mature polypeptide of SEQ ID NO: 2, the mature polypeptide of SEQ ID NO: 4, or the mature polypeptide of SEQ ID NO: 6; (b) a GH61 polypeptide encoded by a polynucleotide that hybridizes under high stringency conditions with (i) the mature polypeptide coding sequence of SEQ ID NO: 1, SEQ ID NO: 3, or SEQ ID NO: 5, (ii) the cDNA sequence contained in the mature polypeptide coding sequence of SEQ ID NO: 1, SEQ ID NO: 3, or SEQ ID NO: 5, 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 micrograms/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 65° C.; (c) a GH61 polypeptide encoded by a polynucleotide having at least 90% sequence identity to the mature polypeptide coding sequence of SEQ ID NO: 1 or the cDNA sequence thereof, the mature polypeptide coding sequence of SEQ ID NO: 3 or the cDNA sequence thereof, or the mature polypeptide coding sequence of SEQ ID NO: 5 or the cDNA sequence thereof; and (d) a fragment of the GH61 polypeptide of (i), (ii), or (iii), that has cellulolytic enhancing activity.
