Synchrotron SAXS data from solutions of Human Collagen Galactosyltransferase GLT25D1/COLGALT1 in 25 mM HEPES, 0.1 M NaCl, pH 8 were collected on the BM29 beam line at the ESRF storage ring (Grenoble, France) using a Pilatus3 2M detector at a sample-detector distance of 2.9 m and at a wavelength of λ = 0.099187 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 mg/ml was injected at a 0.06 ml/min flow rate onto a GE Superdex 200 Increase 3.2/300 column at 20°C. 1200 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.
