Additional file 2: Figure S1. Structural alignment of the model generated with Swiss Model using as template the endoglucanase from Fervidobacterium nodosum (FnCel5A) in complex with substrate alpha-D-glucopyranose (3rjy.1.A, green); the endoglucanase from Thermotoga maritima (TmCel5A) in complex with cellobiose (3azr.1.A, yellow) and the inactive mutant endoglucanase from Clostridium thermocellum [4u5i.1.A, CtCel5E (E314A)] in complex with xylobiose (light blue). Substrates and conserved residues linked to the catalytic activity are represented in ball-and-stick model.
