Figure 6
(a) OMIT map and (b) polder map for ligand ABI 246 in PDB entry 1c2k. The positive and negative mFobs − DFmodel OMIT difference density contoured at 3σ is displayed in green and red, respectively. (c) OMIT map contoured at ±2σ, at which the ligand density has a similar shape as the polder map. The gray sphere represents a Zn ion. |
