Hydration sites of Ala conformers of (a) α-helical and (b) extended β-sheet secondary structure. Positions of hydration sites are shown as spheres and their occupancies and distances to the nearest polar atoms are labelled. In the α-helical conformation the water distribution is contoured at an occupancy level of 0.10 waters per amino acid using a mesh. In the β-sheet conformation it is contoured at occupancy levels of 0.04 and 0.08. |
