Figure 2
Distribution of hydrophobicity around tryptophan and arginine residues. The side chains of tryptophan (a, b) and arginine (c, d) are shown in either ball-and-stick (a, c) or molecular-surface (b, d) representation. Ball-and-stick representations are coloured by atom type, whereas the surface representation is coloured by GRID-assigned hydrophobic potential. Here, yellow indicates regions with high local hydrophobicity, while purple indicates nonhydrophobic surface patches. |
