Figure 2
Strain energies (left axis; kJ mol−1) and RSZD scores (right axis) for QR of bacteriorhodopsin as a function of the occupancy of the all-trans conformation (the occupancy of the 13-cis conformation is always 100% minus this occupancy). Strain energies are shown for the all-trans conformation, the 13-cis conformation and for their sum. RSZD scores are shown for Lys216, retinal and their sum. Raw data are given in Supplementary Table S1.
