Figure 1: Identification of the Gefitinib binding pocket in EGFR kinase domain.

(A) Schematic illustration of EGFR receptor on the cell membrane. (B) The gefitinib binding pocket was calculated at the distance of 3 Å using Maestro. The identified ligand binding pocket is shown in 2D. Residues are colored according to their properties (red, negatively charged; blue, positively charged; cyan, polar; green, hydrophobic; and white, neutral). The H-bond is shown with magenta arrow.
