North, east and N populations of the ribose moieties from the MD trajectory along the last 14.5 ns, N populations from 3J(H,H) coupling constants (4) and RDCs (10). Populations from coupling constants and RDCs were obtained assuming a two-state equilibrium between N (P = 270–90°) and S (P = 90–270°). North, south and N populations from the MD trajectory were calculated from the fraction of P = 315–45°, P = 45–135° and P = 270–90°, respectively.
