Figure 2
Isosurface rendering of the equatorial domain of the single particle reconstruction (left, blue) and the docked crystal structure filtered in the same way as the single particle reconstruction (right, green). The arrows indicate one point where the helices are apparently bridged in both structures. At higher isosurface thresholds this bridge can be eliminated in both structures.
