Synchrotron SAXS data from solutions of C-terminal binding protein 1 mutant (CtBP1: R266A, D290A, E295A, H315A) in 50 mM HEPES, 150 mM NaCl, 1 mM TCEP, 5% v/v glycerol, pH 7.2 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 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 0.61 mg/ml was measured at 20°C. 40 successive 0.200 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.

Tetramerization mutant.
