| + | [https://www.uniprot.org/uniprot/CBHB_ASPFU CBHB_ASPFU] The biological conversion of cellulose to glucose generally requires three types of hydrolytic enzymes: (1) Endoglucanases which cut internal beta-1,4-glucosidic bonds; (2) Exocellobiohydrolases that cut the dissaccharide cellobiose from the non-reducing end of the cellulose polymer chain; (3) Beta-1,4-glucosidases which hydrolyze the cellobiose and other short cello-oligosaccharides to glucose. | ||

| + | == Publication Abstract from PubMed == | ||
| + | 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 A, 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. | ||
