Patent ID: 8865446

Claim:
A nucleic acid construct or recombinant expression vector comprising an isolated polynucleotide sequence that encodes a GH61 polypeptide, wherein the polynucleotide sequence is operably linked to one or more heterologous control sequences that direct production of the polypeptide in an expression host, wherein the GH61 polypeptide having cellulolytic enhancing activity is selected from the group consisting of: (a) a GH61 polypeptide comprising an amino acid sequence having at least 95% sequence identity to amino acids 19 to 349 of SEQ ID NO: 4; and (b) a GH61 polypeptide encoded by a polynucleotide comprising a nucleotide sequence having at least 99% sequence identity to nucleotides 55 to 1099 of SEQ ID NO: 3, or a GH61 polypeptide encoded by the cDNA sequence of nucleotides 55 to 1099 of SEQ ID NO: 3.
