Isotherms of TmCBM27 Binding to Mannotetraose (A) and Mannohexaose (B and C) Obtained by Isothermal Titration Calorimetry
(A and B) The titration of mannooligosaccharides into TmCBM27 (150 μM). The solid line through the data in (A) shows the fit of the data to a bimolecular interaction model, whereas the solid line in (B) shows the trend only.
(C) The titration of TmCBM27 (1.6 mM) into mannohexaose (150 μM). The solid line through the data shows the fit to binding model treating mannohexaose as a divalent acceptor.

Association of TmCBM27 with Mannohexaose as Measured by Dynamic Light Scattering
(A) The change in measured molecular weight with the addition of mannohexaose. The solid line represents the fit of the data by nonlinear regression to the proposed binding model (see text). Error bars represent the standard error of duplicate sample.
(B) The dependency of monomer (filled symbols) and dimer (open symbols) species concentrations on mannohexaose addition for the experimental data (circles) compared with the theoretical values calculated from the model (squares).

Proposed Equilibria Describing Mannohexaose Recognition by TmCBM27
P, TmCBM27; L, mannohexaose. Ka,m and Ka,d are the equilibrium association constants for the formation of the monomeric complex and the dimeric complex, respectively.

Isotherm Obtained by the Titration of TmCBM27 (2.53 mM) into Carob Galactomannan (0.19 g/l) as Measured by ITC
Data is present in the standard format of energy evolved per injection (A) and in Scatchard form (B). The solid line in (A) shows the trend only.

6. Figure 5 Three-Dimensional Structure of Uncomplexed TmCBM27
(A) The overall secondary structure of the protein is shown with the aromatic amino acids in the binding site shown in “licorice.” The bound metal ion is shown as a blue sphere. Solvent-accessible surfaces of TmCBM27 complexed with (B) G2M5 and (C) mannohexaose. Purple regions indicate the surface contributed by the binding site aromatic residues. The sugar molecules are shown in blue and red licorice.

Observed Electron Density for G2M5 (A) and Mannohexaose (B) Bound to TmCBM27
All maps are maximum-likelihood (Murshudov et al., 1997)/σA-weighted (Read, 1986) 2Fobs – Fcalc electron density maps contoured at 0.55 (G2M5) and 0.43 (mannohexaose) electrons/Å3. Aromatic residues involved in binding are shown in licorice.
