    The enzymatic degradation of plant cell-wall cellulose is central to many industrial processes, including second-generation biofuel production. Key players in this deconstruction are the fungal cellobiohydrolases (CBHs), notably those from family GH7 of the carbohydrate-active enzymes (CAZY) database, which are generally known as CBHI enzymes. Here, three-dimensional structures are reported of the Aspergillus fumigatus CBHI Cel7A solved in uncomplexed and disaccharide-bound forms at resolutions of 1.8 and 1.5 Å, respectively. The product complex with a disaccharide in the +1 and +2 subsites adds to the growing three-dimensional insight into this family of industrially relevant biocatalysts.
