Abstract excerpt
The cellulose-binding domains (CBDs) of fungal cellulases interact with crystalline cellulose through their hydrophobic flat surface formed by three conserved aromatic amino acid residues. To analyze the functional importance of these residues, we constructed CBD mutants of cellobiohydrolase 1 (CBH1) of the thermophilic fungus Humicola grisea, and examined their cellulose-binding ability and enzymatic activities....
