FIGURE 9.

Comparison of the sugar binding pockets found in the glucan-binding domains of ΔN₁₂₃-GBD-CD2 (complex C), and putative sugar binding pockets of GTF180-ΔN (PDB entry 3KLK) and GTFA-ΔN (PDB entry 4AMC) glucansucrases. Secondary structure elements are shown in pale red in agreement with Fig. 9. Molecular surfaces are displayed in light gray. Residues delineating the binding pockets are shown as pale red sticks. Stacked sugars in the binding pockets of ΔN₁₂₃-GBD-CD2 are represented in yellow lines.
