Figure 8
Example of the incorrect interpretation of an electron-density map that can be detected on the basis of multiple side-chain conformation changes made by Fitmunk. (a) Original deposition with PDB code 4emh (yellow lines) shown with 2mFoDFc (blue; at the 1 r.m.s.d. level) and mFoDFc (green, positive; red, negative; both at the 3 r.m.s.d. level) electron-density maps. Multiple regions of low model–data correspondence can be seen. (b) Model refined with Fitmunk. All incorrectly fitted side chains have been corrected. (c) Fragment of a screenshot from the Fitmunk server showing differences between the original model and the model refined with Fitmunk. Analysis of regions with multiple differences led to the identification of the fragments shown in (a) and (b).
