Figure 7. Location of ECL3 inside the binding pocket.

The interacting residues on ECL3 (IFTPPKQ) were located in the middle of the binding pocket. The surface representation of binding pocket showed that the interacting portion of ECL3 was surrounded by N-terminal region (pink) and ECL2 (red). The amino acids were colored according to their properties (i.e. nonpolar residues white, polar ones green and basic residue as blue).
