Figure 5.
Fig. 5. Cu^+- and Ag^+-binding sites of molecule A of CusB. Cu^+ and Ag^+ ions are represented by purple and green spheres, respectively. The overall locations of sites C1, C2, and A1 are circled. Anomalous difference Fourier maps are contoured at 4.6 σ, 4.0 σ, and 4.2 σ for sites C1, C2, and A1, respectively. Anomalous peak heights for sites C1′, C2′, and A1′ in molecule B of CusB (not shown) were found to be 4.6 σ, 4.6 σ, and 5.4 σ, respectively.
