Molecular characterization of a cell wall-associated beta(1-3)endoglucanase of Aspergillus fumigatus.

A 74 kDa beta(1-3)endoglucanase of Aspergillus fumigatus was recently isolated from a cell wall autolysate and biochemically characterized. In this study, we report the cloning and the disruption of the ENGL1 gene encoding this beta(1-3)endoglucanase. ENGL1 contains an open reading frame of 2181 bp encoding a polypeptide of 727 amino acids.
