GroEL apical and equatorial domains, atomic and density representations. Close-up of an all-atom representation of the (a) apical and (b) equatorial domains. The blue envelope surrounding each is an isosurface of the density (15 Å Fourier cutoff) derived from each. These low-resolution density maps are the search objects that are correlated with the cryo-EM map in order to find the positions of the domains in the EM map of the complete oligomer. It is apparent that at 15 Å sharp features are smoothed and side chains extending out from the surface are rounded off. The atomic domains and maps were displayed in O. |
