Figure 6.
EISF, A0, for the two forms of rOPN from fits (lines) by Eq. 7. The fraction of immobile atoms, at the resolution times of each spectrometer, is shown for each plateau: (A) IN16B QENS spectra (∼4 ns); see also Fig. S11 for more information on the fit parameters. (B) IRIS spectra (∼15 ps). The effective radius a is 2.63 ± 0.86 Å and 2.71 ± 0.36 Å for unphosphorylated and phosphorylated rOPN, respectively. The data point error bars correspond to 1 SD of uncertainty.
