Further confirmation of the 2:2 turn was done by visualizing this turn in detail for AM-BER14SB (Figure ) and CHARMM36 (Figure ). The 2:2 turn is present in both force fields at the expected dihedral interactions. Taken together, these findings reinforce the idea that inverse distance featurizations are sufficient to capture the conformational dynamics of chignolin, and that inclusion of dihedral angle featurizations for chignolin can lead to undesirable artifacts.
