FIGURE 3

Stereoviews of low-energy conformers of the IC1+IC2+IC3 (a) and EC1+EC2+EC3 (b) packages compared to snapshots from the five x-ray structures of rhodopsin in the R state. Loops IC1 and EC1 are shown in red, IC2 and EC2 in green, and IC3 and EC3 in blue. Loop conformers are shown as one-line ribbons. The x-ray snapshots are shown as tubes in magenta. The TM region of rhodopsin is shown as a five-line ribbon in cyan. Views are from the intracellular (a) and extracellular (b) sides of membrane, respectively.
