FIG 5.

Atomic models of truncated SopB/SigE complexes. (A) For each atomic model, the chaperone dimer SigE is represented with clear blue beads and the different parts of SopB with blue spheres for SopBΔ29, green spheres for SopBΔ112, and red spheres for SopBΔ144. The different models are presented in two orientations, and the monomeric part is highlighted with a cartoon model (blue for SigE and yellow for SopB). (B) Superimposition of experimental and calculated SAXS data from the different complexes. The model was achieved by using a complete model of SigE-SopB and achieved with SASREFMX applying P6 symmetry. Dots connected with colored lines show the experimental SAXS data (red for SigESopBΔ144, green for SigESopBΔ112, and blue for SigESopBΔ29), and black dotted lines show the corresponding curves obtained from the atomic model of each construct.
