Figure 5
Comparison of EM two-dimensional class averages and equivalent views of the Na+-NQR complex in the X-ray structure. The projection of the Na+-NQR crystal structure (top) is depicted next to the most similar EM two-dimensional class average (middle) and an individual Na+-NQR particle that has been filtered to 13 Å and aligned with the two-dimensional class average (bottom). Two-dimensional class averages with a particularly pronounced resemblance to certain views of the X-ray map are depicted. The scale bar represents 50 Å.  [article HTML]
