Figure 2.

Experimental SAXS profiles for (a) Dss1, (b) ProT$\alpha$, (c) NHE6cmdd, and (d) ANAC046. Experimental intensities are shown as black squares with gray error bars (representing the experimentally determined errors rescaled as described in the materials and methods). The inserts show the linear fit (red line) in the Guinier region (identified with the autorg tool of the ATSAS package (40)) for each profile, and the resulting $R_{\mathrm{g}}$ value.
