Probability distribution and average number of water molecules in the first hydration shell of the bulge base.

<p>(a) Probability distribution of water molecules in the first hydration shell around the A-bulge base in structure I for different pressures at K for structure I. Note that the probability of or water molecules increases as the pressure is increased. (b) Ensemble averaged as a function of pressure.
