Figure 3
Segmented EF-G density from the maps obtained for the EF-G-containing class in three-dimensional maximum-likelihood refinements using a real-space (ab) or reciprocal-space (cd) target function and a Gaussian (bd) or a t-mixture model with six degrees of freedom (ac). Superimposed on the (transparent) densities obtained with the Gaussian mixture model are the positive (green) and negative (red) difference maps, i.e. the density obtained with the t-mixture minus the density obtained with the Gaussian mixture. All maps, including the difference maps, are rendered at the same isosurface value.
