Structural changes in the MSP1E3D1:DMPC nanodisc across the phase transition temperature of the DMPC bilayer. The scattering data were collected at 283 K (blue symbols) and 303 K (red symbols). The solid black lines show the WillItFit results (up to q = 0.6 Å−1). The left inset replots the wide-angle portion of the scattering data (symbols) on a linear intensity scale, compared with two Lorentzian functions (solid lines) as references for peak symmetry. The 283 K data (blue) show a higher intensity on the low-q side of the peak. The pair distance distribution functions (middle inset, same colour code) derived from the data show a larger maximum dimension and the protein belt peak (indicated by the triangle, as discussed in §3.3[link]) shifting to a larger distance at 303 K. The right inset shows the electron-density profile of the bilayers based on the WillItFit results (Table S2 in the supporting information).
