Synchrotron SAXS data from solutions of Microtubule affinity regulating kinase (isoform MARK1) in 0.1 M Bis-Tris, 0.2 M ammonium citrate, 1mM DTT, pH 6.5 were collected on the EMBL X33 beam line at the DORIS III, DESY storage ring (Hamburg, Germany) using a MAR 345 Image Plate detector at a sample-detector distance of 2.7 m and at a wavelength of λ = 0.15 nm (I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). Solute concentrations ranging between 0.5 and 6 mg/ml were measured . Two successive 120 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. The low angle data collected at lower concentration were merged with the highest concentration high angle data to yield the final composite scattering curve.
