Schematic representation of the recombinant proteins. The bacterial origins of the representative modules are shown by color coding in the pictograms. In the shorthand notation for the recombinant enzymes, the numbers 9, 48, 5, 6, 1, 43, 11, and 10 correspond to the GH (glycoside hydrolase) family of the catalytic modules, uppercase characters indicate the bacterial origin of the cohesin modules, and T2 specifies a type II cohesin. The bacterial origin of a given dockerin module is indicated by a lowercase italic character. The wild-type T. fusca cellulases (except Bgl1C) and xylanase Xyn10A contain a cellulose-specific family 2 CBM. The CBMs of the chimeric scaffoldins are derived from the family 3a CBM from C. thermocellum CipA. Wild-type and recombinant forms of Cel9A contain a family 3c CBM.
