Synchrotron SAXS data from solutions of The CxxC-linker-CxxC construct binding 1 Cd(II) ion in a CdCys4 site in 10 mM Tris, 50 mM NaCl, pH 7.4 were collected on the EMBL P12 beam line at the PETRA III storage ring (DESY; Hamburg, Germany) using a Pilatus 6M detector at a sample-detector distance of 3.1 m and at a wavelength of λ = 0.124 nm (I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). One solute concentration of 5.76 mg/ml was measured at 20°C. 80 successive 0.100 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.
