Modeling Beta-Traces for Beta-Barrels from Cryo-EM Density Maps

Figure 6

β-Strands modeling from the simulated density map at 10 Å. The best of the fifteen sets of modeled β-traces (red) are superimposed with the backbone of β-strands (blue) and the density maps (gray) for β-barrels 1G7K_A13 in (a) and 2GUF_D23 in (b). The top view (left) and four side views are shown in each case.
