Synchrotron SAXS data from solutions of the complex formed between E. coli S-adenosylmethionine synthase and wild-type S-adenosyl-L-methionine lyase from bacteriophage T3 in 50 mM Tris-HCl, 300 mM NaCl, 5 mM β-mercaptoethanol, 2 % glycerol, pH 7.5 were collected on the B21 beam line at the Diamond Light Source (Didcot, UK) using a Eiger 4M detector at a sample-detector distance of 4.0 m and at a wavelength of λ = 0.09998 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 50.00 μl sample at 4.9 mg/ml was injected at a 0.16 ml/min flow rate onto a Shodex KW403 column at 25°C. Nine successive 3 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.
