Figure 7From: A graph theoretic approach to utilizing protein structure to identify non-random somatic mutationsThe KRAS structure (PDB ID 3GFT) color coded by region: amino acids 13–22 are blue, 24–60 are red and 62–145 are yellow. Residues 12 and 13 which make up the most significant cluster are shown as purple spheres, while residues 23, 61, 117 and 146 are shown as brown spheres.Back to article page
