Figure 5

Equilibrium fluorescence titrations of P4–P6 derivatives labeled with pyrene at U247, U249, U253, A246, A256 or C240. For each of the five tethers, the fluorescence spectra were qualitatively similar to those for U107 that are depicted in Figure 4 (data not shown). See Supplementary Data for [Mg2+]1/2 values.
