Figure 2
Visualization of two ligands from the PDB together with electron-density maps. The LiteMol viewer (Sehnal et al., 2017 ) on the PDBe website (Mir et al., 2018 ) has been used to visualize the ligands with EDS-style (Kleywegt et al., 2004 ) electron-density maps. In each case, the 2mFo − DFc map is shown as a blue mesh contoured at 0.39 e Å−3, whereas the mFo − DFc difference map is shown by solid green and red surfaces contoured at +0.25 and −0.25 e Å−3, respectively. (a) Model and electron density for the well placed ligand 468 from PDB entry 4tzt (He et al., 2006 ). (b) The ligand DIF in PDB entry 3ib0 (Mir et al., 2009 ). |
