Fig 5. SAXS data and analysis on KISS1.

(A) Logarithmic (top) and Kratky (bottom) representations of SAXS intensity versus momentum transfer s (open circles). (B) Averaged back-calculated curves derived from a statistical random coil ensemble (black line) and EOM selected sub-ensemble (red line). The goodness-of-fit is indicated by χ² values. The bottom panel shows the residuals of the fitting for both conformational ensembles. (C) Distribution of the radius of gyration, Rg, in the random coil ensemble (gray-bars) and EOM selected sub-ensemble, where a shoulder peak around 50 Å contains ca. 30% of all conformers.
