5. Experiment Description and Publication Experiment & Publication
Original Experiment Description
Synchrotron SAXS data, I(s) vs s (s = 4π sin θ/λ, where 2θ is the scattering angle) were collected from a sample of truncated SecA (amino acids 1-880) using continuous-flow size-exclusion chromatography SAXS (SEC-SAXS) on the BM29 beam line at the ESRF (Grenoble, France). Data were collected using a Pilatus 1M detector at a sample-detector distance of 2.9 m and at a wavelength of λ = 0.0919 nm. The SEC mobile phase consisted of 20mM HEPES, 100mM NaCl, 1mM TCEP, pH 8 (20°C). Data obtained from solute-free eluates and SEC-elution peak (69 successive 1 s data frames) were normalized to the intensity of the transmitted beam and radially averaged; the scattering of the solvent-blank was subtracted from the SEC-peak frames to produce the data displayed in this entry.
