Abstract excerpt
The nag1 gene of the mycoparasitic fungus Trichoderma atroviride encodes a 73-kDa N-acetyl-beta- d-glucosaminidase, which is secreted into the medium and partially bound to the cell wall. To elucidate the role of this enzyme in chitinase induction and biocontrol, a nag1-disruption mutant was prepared. It displayed only 4% of the original N-acetyl-beta- d-glucosaminidase activity, indicating that the nag1 gene...
