Structural features captured by the KB potential. The plots (A–C) show the potentials for specific atom pairs. In each plot, the corresponding force is shown in the inset. (A) gC4-gC4 potential showing a base-stacking well ∼4.4 Å labeled (1). (B) uC4-uC4 potential showing no base-stacking well. (C) gO6-cN4 potential showing a deep base-pairing well (2a) and various structural wells (2b and 2c). (D) Distances represented in the different wells shown on the Rev binding element of HIV-1 structure (PDB id: 1duq).
