Figure 4
Heatmaps describing the relationship (combined distribution function) involving the distances from the metal ion to Oδ1/Oδ2 (left column, Asp) and to Oɛ1/Oɛ2 (right column, Glu). The heatmaps were plotted using data from all of the analyzed resolution ranges. The top row represents the data for magnesium(II), whereas the bottom row represents the data for calcium(II). The deeper the blue, the more data are present in that region. It can be observed that bidentate coordination is only common for calcium(II), corresponding to the peak at about (2.5, 2.5), especially in the case of Glu coordination (bottom right plot). The scale refers to the number of structures in an area of 0.05 × 0.05 Å. |
