Redistribution of the Pre-complex subpopulations in 10 mM Mg²⁺ or 4.5 mM Mg²⁺ buffers, or bound with Viomycin. The color codes for the subpopulations are shown in the plot. With decreasing Mg²⁺ concentrations, F-High increases mainly at the expense of decreasing NF-Low, whereas in the presence of Viomycin, F-High increases mainly at the expense of decreasing F-Low. The error bars are calculated from at least three independent measurements.
