Synchrotron SAXS data from solutions of Light-state LOV-activated diguanylate cyclase in 10 mM Tris, 50 mM NaCl, 2 mM MgCl2, 3% glycerol, pH 8 were collected on the BM29 beam line at the ESRF storage ring (Grenoble, France) using a Pilatus3 2M detector at a sample-detector distance of 2.9 m and at a wavelength of λ = 0.125 nm (I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). One solute concentration of 1.00 mg/ml was measured at 20°C. 10 successive 1 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.

Sample preparation and measurment performed under actinic light conditions (blue light). Sample measurement in batch mode.
