SAXS data from solutions of CbpD in 15 mM Tris-HCl 150 mM NaCl, pH 7.5 were collected using a Bruker Nanostar instrument with an InCoatec Cu microsource (RECX, University of Oslo, Norway) equipped with a Våntec-2000 detector at a wavelength of λ = 0.154 nm (I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). One solute concentration of 2.18 mg/ml was measured at 24°C. Two successive 3600 second frames were collected. The data were normalized to the intensity of the transmitted beam and radially averaged; the scattering of the solvent-blank was subtracted.

For the dummy-atom model representations: An individual DAMMIF model with the corresponding fit to the data is displayed along with a damfilt representation generated from the spatial alignment of nine individual models.
