31P Chemical Shifts and Linewidths Measured from the NMR Spectra of DMPC:SMA-QA (1:0.5 w/w) Macro–Nanodiscs in the Absence (Column 1) and Presence of YbCl3 (Columns 2–4) at Different Temperatures, as Shown in Figure 3a,b.
| temperature (K) | 0 mM YbCl3 | 0.5 mM YbCl3 | 1 mM YbCl3 | 1.5 mM YbCl3 |
|---|---|---|---|---|
| 305 | −13.4 ppm (181 Hz) | 19.9 ppm (2741 Hz) | 16.5 ppm (1265 Hz) | 12.0 ppm (1723 Hz) |
| 310 | −13.8 ppm (272 Hz) | 22.6 ppm (1265 Hz) | 18.8 ppm (1355 Hz) | 14.9 ppm (1841 Hz) |
| 315 | −14.3 ppm (365 Hz) | 23.8 ppm (1292 Hz) | 20.1 ppm (1359 Hz) | 15.5 ppm (1933 Hz) |
a
Unlike the samples used to obtain the spectra given in Figure 2, free polymers were removed using SEC for these macro–nanodisc samples.
b
Line widths are shown in parentheses.
