Fig. 4.

Ligand-receptor interactions. a) Docking best pose; the ligand is shown as vdW spheres, for RXRα (in blue) and FXR (in light green) are shown the solvent-accessible surfaces as calculated using the Connoly algorithm. (b) LigPlot+ 2D schematic representation of the ligand best pose in the heterodimeric receptor binding site. The ligand intramolecular bonds are shown in purple, the receptor amino acids involved in the interaction are shown in black (hydrophobic interactions) and in green (H-bonds). H-bonds are depicted as dashed green lines, together with distances in angstroms.
