Electron-density and difference density maps for PDB entry 5kco after re-processing in autoPROC and re-refinement in BUSTER. The 6RO compound is shown with surrounding protein residues, a 2mFoDFc density map at 1.0 r.m.s. and mFoDFc difference density at 3.5 r.m.s.. The occupancy and isotropic B factor for the Cl atom are shown close to that atom, while those for the non-Cl atoms are shown below the compound. (a) Deposited model of 6RO in PDB entry 5kco. (b) After re-processing the raw diffraction data with autoPROC and refining a single occupancy over all compound atoms. (c) F(early) − F(late) map at 5.0 r.m.s. showing a strong peak at the Cl atom. (d) After using separate occupancy parameters for the Cl and non-Cl compound atoms.
