Figure 2
An example of an Fo − Fc omit map for visualization of ligand density. The ligand molecules and ions shown as sticks and spheres, respectively, are omitted in the map calculation. The resolution is (a) 2.08 Å (PDB entry 7kjr/EMDB entry EMD-22898) and (b) 3.6 Å (PDB entry 5it7/EMDB entry EMD-8123). The Fo − Fc omit maps are contoured at 3σ (where σ is the standard deviation within the mask; see Section 3.3). The images were created using PyMOL (Schrödinger, 2020). |
