Synchrotron SAXS data from solutions of Saccharomyces cerevisiae Mer2 coiled-coiled with N-terminal SUMO-tag in 25 mM HEPES-NaOH, 500 mM NaCl, 5 mM EDTA, 5% glycerol, 1 mM DTT, pH 7.5 were collected on the SWING beam line at the SOLEIL storage ring (Saint-Aubin, France) using a Eiger 4M detector at a sample-detector distance of 2 m and at a wavelength of λ = 0.099 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 90.00 μl sample at 10.5 mg/ml was injected at a 0.20 ml/min flow rate onto a Shodex KW404-4F column at 15°C. 960 successive 0.990 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.
