experiment_descriptionSynchrotron SAXS data from solutions of PgaB in phosphate-buffered saline, pH 7.4 were collected on the BL4-2 beam line at the Stanford Synchrotron Radiation Lightsource (SSRL; Menlo Park, CA, USA) using a Pilatus3 X 1M detector at a sample-detector distance of 1.7 m and at a wavelength of λ = 0.1127 nm (I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). In-line size-exclusion chromatography (SEC) SAS was employed. The SEC parameters were as follows: A 0.05 μl sample at 8 mg/ml was injected at a 0.05 ml/min flow rate onto a GE Superdex 200 Increase 10/300 column at 20°C. Four successive 0.100 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.

  "experiment_description": "Synchrotron SAXS data from solutions of PgaB in phosphate-buffered saline, pH 7.4 were collected on the BL4-2 beam line at the Stanford Synchrotron Radiation Lightsource (SSRL; Menlo Park, CA, USA) using a Pilatus3 X 1M detector at a sample-detector distance of 1.7 m and at a wavelength of λ = 0.1127 nm (I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). In-line size-exclusion chromatography (SEC) SAS was employed. The SEC parameters were as follows: A 0.05 μl sample at 8 mg/ml was injected at a 0.05 ml/min flow rate onto a GE Superdex 200 Increase 10/300 column at 20°C. Four successive 0.100 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.",
