  1. aAll amino acid residues were within 5 Å from the ligand surface and 10 Å from the centroid of the ligands.
  2. bThese amino acid residues though not visible in the figures, were actually on the rear side of this 3D pose and were observed in the interaction energy tables,as well as, in other poses.
  3. cEzetimibe was taken as reference native ligand for better comparison.
  4. dNative ligand as co-crystallized in the PDB 3D structures.
