Synchrotron SAXS data from solutions of Truncated P5abc subdomain from tetrahymena ribozyme: (Time-resolved 100ms) in 10mM KMOPS 20mM KCl 1mM MgCl2 20uM EDTA, pH 7 were collected on the G1 beam line at the Cornell High Energy Synchrotron Source (CHESS; Ithaca, NY, USA) using a CCD Finger Lakes CCD detector at a sample-detector distance of 1.7 m and at a wavelength of λ = 0.109 nm (I(s) vs s, where s = 4πsinθ/λ and 2θ is the scattering angle). One solute concentration of 1.50 mg/ml was measured at 20°C. 50 successive 5 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.
