Patent ID: 7045332

Claim:
An isolated polynucleotide encoding a glycosyl hydrolase Family 3 β-glucosidase enzyme having β-glucosidase activity from a fungal source, which polynucleotide comprises a nucleotide sequence encoding an enzyme having β-glucosidase activity selected from the group consisting of: (a) a nucleic acid sequence which encodes or is complementary to a sequence which encodes a β-glucosidase 4 polypeptide having at least 98% sequence identity to the amino acid sequence presented in FIG. 2 ; (b) a nucleic acid sequence which encodes or is complementary to a sequence which encodes a β-glucosidase 4 polypeptide having the amino acid sequence presented in FIG. 2 ; and (c) a nucleic acid sequence presented as SEQ ID NO:3, or the complement thereof; wherein % identity is calculated using the CLUSTAL-W program in MacVector version 6.5, operated with default parameters, including an open gap penalty of 10.0, an extended gap penalty of 0.1, and a BLOSUM 30 similarity matrix.
