Solution X-ray scattering experiments and determination of the P-CR three-dimensional surface contour structure. A, Log(I) versus q plot of the raw data of the P-CR. B, Kratky plot of the same P-CR data. C, The P(r) pair distribution function for intensity data corresponding to P-CR as calculated by GNOM (Svergun, 1992). D, Three-dimensional molecular envelopes of the P-CR (dark blue) reconstructed from the solution scattering data using the ATSAS software package (Konarev et al., 2006) with GASBOR (Svergun et al., 2001). Molecular surfaces generated from the grid objects that were obtained by averaging multiple reconstruction runs were rendered with Chimera (Pettersen et al., 2004). The P-CR crystal structure (light blue) is shown embedded in its best-fit orientation using MIFit (https://github.com/mifit/mifit).
