Polypeptides Having Cellulolytic Enhancing Activity And Polynucleotides Encoding Same

摘要

The present invention relates to isolated polypeptides having cellulolytic enhancing activity and polynucleotides encoding the polypeptides, catalytic domains, cellulose binding domains and polynucleotides encoding the polypeptides, catalytic domains or cellulose binding domains. The invention also relates to nucleic acid constructs, vectors, and host cells comprising the polynucleotides as well as methods of producing and using the polypeptides, catalytic domains or cellulose binding domains.

主权项

1. An isolated polypeptide having cellulolytic enhancing activity, selected from the group consisting of:
(a) a polypeptide having at least 71% sequence identity to the mature polypeptide of SEQ ID NO: 2 or at least 75% sequence identity to the mature polypeptide of SEQ ID NO: 4; (b) a polypeptide encoded by a polynucleotide that hybridizes under at least high stringency conditions with the mature polypeptide coding sequence of SEQ ID NO: 1 or the cDNA sequence thereof, or the mature polypeptide coding sequence of SEQ ID NO: 3; or the full-length complement thereof; (c) a polypeptide encoded by a polynucleotide having at least 71% sequence identity to the mature polypeptide coding sequence of SEQ ID NO: 1 or the cDNA sequence thereof, or at least 75% sequence identity to the mature polypeptide coding sequence of SEQ ID NO: 3; (d) a variant of the mature polypeptide of SEQ ID NO: 2 or SEQ ID NO: 4 comprising a substitution, deletion, and/or insertion at one or more positions; and (e) a fragment of the polypeptide of (a), (b), (c), or (d) that has cellulolytic enhancing activity; and (f) a polypeptide comprising or consisting of SEQ ID NO: 2, SEQ ID NO: 4, the mature polypeptide of SEQ ID NO: 2, or the mature polypeptide of SEQ ID NO: 4.
