Table 1 SAXS parameters.

Parameters pertaining to the Pr state were derived from absolute scattering data. The Pfr parameters were derived from reconstructed scattering curves, obtained by adding the difference curves (Fig. 3) at various assumed levels of conversion. The parameters Rg and I0 were estimated using conventional Guinier analysis. See table S1 for a more extensive version of this table.
