Synchrotron SAXS data from solutions of Sinorhizobium meliloti proline utilization A (PutA) in 50 mM Tris, 1% (v/v) glycerol, 0.5 mM THP and 50 mM NaCl, pH 7.8, were collected on the 12.3.1 SIBYLS beam line at the Advanced Light Source storage ring (ALS; Berkeley, CA, USA) using a MAR 165 CCD detector at a wavelength of λ = 0.1127 nm (l(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). One solute concentration of 4.00 mg/ml was measured at 10°C. The data were normalized to the intensity of the transmitted beam and radially averaged; the scattering of the solvent-blank was subtracted.
The fit to the SAXS data is shown for a volume-fraction weighted mixture of monomers and dimers. The volume fraction of monomer and dimer are 0.48 and 0.52, respectively. |
