Synchrotron SAXS data from solutions of N-terminal domain of Diguanylate cyclase with PAS/PAC sensor (Maqu_2914) from Marinobacter aquaeolei, Northeast Structural Genomics Consortium Target MqR66C in 5 mM DTT 100 mM NaCl 10 mM Tris-HCl 0.02 % NaN3, pH 7.5 were collected on the BL4-2 beam line at the Stanford Synchrotron Radiation Lightsource (SSRL) storage ring (Menlo Park, CA, USA) using a Rayonix MX225-HE detector at a sample-detector distance of 1.5 m and at a wavelength of λ = 0.13 nm (I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). Solute concentrations ranging between 2.6 and 7.1 mg/ml were measured at 20°C. 20 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.
