Representative isothermal titration calorimetry (ITC) data of CtCBM3acipA-M5 titrated with carbohydrates. The soluble ligand (10 mg/mL in the syringe) was titrated into 54 μM CtCBM3acipA-M5 in the cell. In the case of cellulose the CBM was titrated into cellulose in the cell. The top half of each titration shows the raw injection heats; the bottom half, the integrated peak areas fitted using a single-site model (MicroCal Origin v7.0). ITC was carried out in 50 mM Na-HEPES pH 7.5 at 25°C.
