Figure 6
Evidence of model bias in electron-density maps produced by EDS. Shown are 1.93 Å resolution electron-density maps of the same region of the concanavalin A–peptide complex (PDB entry 1jw6; rank 116; Zhang et al., 2001) as calculated by EDS (a), PDB_REDO (b) and by BUSTER-TNT after refinement of the model with the peptide molecule omitted (c). The peptide is shown in yellow; the protein model has been omitted for clarity. |
