Zn1702, chain B, from jumonji H3K27 demethylase (PDB entry 4eyu; Kruidenier et al., 2012). mFo − DFc difference electron-density maps after a PDB_REDO run with (a) an isotropic B factor for Zn2+ (grey sphere) or (b) an anisotropic B factor for Zn2+ (grey thermal ellipsoid). The maps (positive, green mesh; negative, red mesh) are contoured at 3σ, are rendered with a grid size of 0.77 Å and for clarity are shown only in the vicinity of the Zn. The largest atomic displacement between any atom in this ZnCys4 complex between (a) and (b) is 0.16 Å. |
