Figure 1
(a) Deposited structure of bacteriorhodopsin (PDB entry 5b6w). (b) QR structure with 85% occupancy for the all-trans state (cyan) and 15% occupancy for the 13-cis state (magenta). This figure also shows the QM region used in the quantum refinements of bacteriorhodopsin. The 2mFo − DFc maps are contoured at 1σ.
