Figure 1
Composite OMIT maps of the binding site at His15 in chains A (a) and B (b) coordinating to fac-[Re(CO)3(H2O)2N] (the N atom is from His15). The 2Fo − Fc electron-density map contoured at 1.2 r.m.s. is shown in blue and the Fo − Fc electron-density map contoured at 5.0σ (the Coot default; Emsley & Cowtan, 2004BB19) is shown in green; the anomalous electron-density map contoured at 3.0σ is shown in orange. This figure was prepared using CCP4mg (McNicholas et al., 2011BB37).
