The average and fluctuations of right- and left-handed GpA dimers were calculated from 2.6-ns trajectories (after 0.6 ns) for each run. The trajectory for the D2 simulation in Table 3 was used for the right-handed configuration.
The buried surface area was calculated using the contact surface defined by the van der Waals radii.
The tilt angle is defined the same as in Table 3.
