Figure 7

The network of water molecules modulating the ligand selectivity of tmCBP. (a) View of the LR5 water network. Water molecules found interacting with the LR5 are shown as blue spheres. The different classes of conserved water molecules also found in the CP5 binding site are colored as follows: red, waters in identical positions coordinating identical atoms; green, waters identical positions coordinating different ligand atoms; black, waters in identical positions forming ligand contacts in one form and not the other; orange, waters mimicking hydroxyl atoms of ligand. (b) View of the CP5 water network. Water molecules found interacting with the CP5 are shown as magenta spheres. The different classes of conserved water molecules also found in the LR5 binding site are colored as in (a).
