The avi2 gene encoding Avi2, which is a major cellulase produced by Humicola insolens FERM BP-5977, was cloned and sequenced. Avi2 showed high homology with other family 6 cellulases. The expression vector pNCE4 containing the avi2 gene was constructed, and this strain was transformed using a protop...
