Synchrotron SAXS data from a solution of Proline utilization A from Bradyrhizobium diazoefficiens (formerly Bradyrhizobium japonicum) in 50 mM Tris (pH 7.8), 50 mM NaCl, 0.5 mM Tris(2-carboxyethyl)phosphine, and 5% (v/v) glycerol, pH 7.8 were collected on the 12.3.1 (SIBYLS) beam line at the Advanced Light Source (ALS; Berkeley, CA, USA) using a Pilatus3 X 2M detector. One solute concentration of 7 mg/ml was measured. The data were normalized to the intensity of the transmitted beam and radially averaged. The radially averaged scattering of the solvent-blank was subtracted.
