Figure 2
Comparison of the quality of the electron-density maps (2mF_o − DF_c) of the PK structures determined using a pink beam (left panels) and a monochromatic beam (Martin-Garcia et al., 2017

) (right panels) contoured at 1.5σ. (a) Electron-density map around the Ca²⁺ site 1. (b) Electron-density map around the Ca²⁺ site 2. Ca²⁺ ions and water molecules are represented as green and red spheres. Residues around Ca²⁺ ions are shown in a stick representation.
