Figure 4
(a) OMIT map and (b) polder map for ligand GRG 502 in PDB entry 4opi. The positive and negative mFobs − DFmodel OMIT difference density contoured at 3σ is displayed in green and red, respectively. (c) OMIT map contoured at ±1.5σ, at which the ligand density has a similar shape to the polder map. |
