Synchrotron SAXS data measured from cyclodipeptide synthase bound to Phe-tRNAPhe in 10 mM MOPS pH6.7;,200 mM NaCl, 8 mM MgCl2 were collected on the SWING beam line at SOLEIL (Saint-Aubin, France) using a Eiger 4M detector at a wavelength of λ = 0.1033 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 sample was injected onto a GE Superdex 200 Increase 3.2/300 column at 15°C. The data were normalized to the intensity of the transmitted beam and radially averaged; the scattering of the solvent-blank was subtracted.
