Synchrotron SAXS data from solutions of the Retriever complex in 50 mM Tris, 200 mM NaCl, 1 mM TCEP, pH 7.5 were collected on the B21 beam line at the Diamond Light Source (Didcot, UK) using a Eiger 4M detector at a sample-detector distance of 3.7 m and at a wavelength of λ = 0.0954 nm (I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). In-line size-exclusion chromatography (SEC) SAS was employed. The SEC parameters were as follows: A 45.00 μl sample at 5 mg/ml was injected at a 0.16 ml/min flow rate onto a Shodex KW403-4F column at 15°C. 600 successive 3 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.
