Supplementary Figure 1: SAXS data for WbdD1–459 monomer.

Two views (rotated by 90°) of an ab initio model constructed using DAMMIN is shown in the bottom left (grey surfaces). The high-resolution structure of WbdD1-459 shown as cartoon model (purple) is superimposed. Fits of the structural model against the experimental SAXS data (open circles with error bars representing s.d. computed from propagated Poisson counting statistics).
