Figure 4

Lowest energy profile of GB or PB implicit solvent models using 1.1 Å or 1.3 Å Hn radii. Each point on a curve represents the average energy of 20 lowest energy structures whose salt bridge distances fall in corresponding distance range (bin size 0.1 Å). Each curve's minimum was zeroed for easier comparison. Error bars in each set were obtained by comparing PMF generated using the first and second half of data.
