Synchrotron SAXS data from solutions of Proline utilization A from Legionella pneumophila in 50 mM Tris-HCl, 50 mM NaCl, 0.5 mM EDTA, and 0.5 mM THP at pH 7.5 were collected on the 12.3.1 (SIBYLS) beam line at the Advanced Light Source (ALS; Berkeley, CA, USA) using a MAR 165 CCD detector (I(s) vs s, where s = 4πsinθ/λ and 2θ is the scattering angle). One solute concentration of 5 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. X-ray wavelength, unknown; Exposure time, unknown; Sample-To-Detector distance, unknown.

Wavelength = UNKNOWN. Cell temperature = UNKNOWN. Storage temperature = UNKNOWN. Sample detector distance = UNKNOWN. X-ray Exposure time = UNKNOWN. Number of frames = UNKNOWN
