"experiment_description": "X-ray synchrotron radiation scattering data from the truncated version of α-DsbA2 from Wolbachia pipientis in 25 mM TRIS 150mM NaCl pH 7.5 were collected on the SAXS/WAXS beam line of the Australian Synchrotron (Melbourne, Australia) using a 2D Photon counting Pilatus 1M-W pixel detector (s = 4π sin θ/λ, where 2θ is the scattering angle). Eight successive 2 second frames were collected across solute concentrations of 1.25-5.00 mg/ml. The SAXS data displayed this entry was derived from a 1.25 mg/ml sample. The data were normalized to the intensity of the transmitted beam and radially averaged and the scattering of the solvent-blank was subtracted. The data were normalized to the intensity of the transmitted beam and radially averaged and the scattering of the solvent-blank was subtracted. The models and corresponding fits include those derived from dummy-atom modelling using DAMMIN (top) and rigid-body modelling using CORAL (bottom).",
