Figure 4
Experimental SAXS curves of ovalbumin collected with the sample changer (top) and with online SEC (bottom; offset by one order of magnitude). The online SEC curve is noisier than the sample changer curve because of the much lower solute concentration, and the higher angle data (for s > 1.5 nm−1) have been re-binned with a binning factor of five for better visualization. The grey lines represent in both cases the fits by the curve computed from the atomic structure. Inset: ab initio model of the ovalbumin monomer (orange) built from the SEC–SAXS experimental curve; the aligned atomic structure is represented in blue for comparison. |
