Figure 5
Coordination of the conserved C-terminal calcium ion of BT2081. Electron density from 2F_o − F_c (contoured at 2.5σ level) and F_o − F_c (contoured at 3.0σ level) maps is represented as green and blue mesh, respectively. A 13σ level anomalous signal obtained from data collected below the nickel edge was seen for the calcium and is shown here contoured at the 6.0σ level as magenta mesh. Distances between the calcium ion and its ligands are indicated in Å.
