Fig. 6: MgIIGTP-YeiR and MgIIGTP-YjiA preferentially acquire ZnII.

a Free-energy change (ΔG) for metal binding to MgIIGTP-YeiR (red circles) plotted against the intracellular available free energies for metal binding (as described in Fig. 5; black squares and bars). b As a for MgIIGTPγS-YjiA (red circles). Arrows indicate where only a limiting ΔG was determined (thus ΔG > plotted value).
