Lane 1: Same as lane 1 in , top. Lane 2: Same as lane 4 in , top. Lanes 3–5: reactions were carried out in the same way as the one loaded in lane 4 in , top, except for replacing KCl with 20 mM NaCl (lane 3), 20 μM Pb (lane 4), 20 μM Ba (lane 5). Lanes 6–7: Same as lane 4 in , top, except for replacing MES with 10 mM Li-cacodylate (lane 6) or 10 mM Tris–HCl (lane 7).
