Figure 1
Schematic representation of the protocol for ligand identification, shown for adenosine triphosphate (ATP) in the structure of a putative N-type ATP pyrophosphatase (PDB entry 3rk1; Forouhar et al., 2011  ) at 2.3 Å resolution. The (Fo − Fc, αc) difference density map is shown contoured at 1.0σ above the mean; free atoms are shown as balls. The thickness of the visual slab has been adjusted for each image to provide the best view; however, it is reduced in (b) in order to clarify the electron density of interest following protein model display in (a). |
