Synchrotron SAXS data from solutions of Pyrococcus furiosus Box C/D sRNP reconstituted with st-sR6 sRNA bound to substrate D in 50 mM phosphate 500 mM NaCl, pH 6.6 were collected on the BM29 beam line at the ESRF (Grenoble, France) using a Pilatus 1M detector at a sample-detector distance of 2.9 m and at a wavelength of λ = 0.099 nm (I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). One solute concentration of 5.00 mg/ml was measured at 40.1°C. 10 successive 1 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.
