Fig. 6: Comparison between the key transition state (TS8) for the dethreading pathway of ROT9 (left) and ROT11 (right).

The top illustration shows the structures around the macrocycles (side-on view). Atoms other than the skeletal atoms and the interaction-relevant hydrogen atoms were hidden for visual clarity. The reference plains (shown in transparent yellow) are the best-fit planes of the macrocycle. The bottom plots show the electron density (darker red-green-blue colormap with red/blue corresponding to 0–0.3 a.u.) and RDG map (brighter rainbow colormap with the blue to red color scale corresponding to 0.15–0.65 a.u.) which shows the weak interactions, in the best-fit plane of the 24-membered-ring66,67.
