Synchrotron SAXS data from solutions of SARS-CoV-2 non-structural protein 14 (nsp14) in 50 mM Tris, 150 mM NaCl, 5 mM MgCl2, 2 mM β-mercaptoethanol, pH 8.5 were collected on the BM29 beam line at the ESRF (Grenoble, France) using a Pilatus 1M detector at a sample-detector distance of 2.8 m and at a wavelength of λ = 0.1 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 100.00 μl sample at 4 mg/ml was injected onto a Agilent Bio SEC-3, 300 Å column. 21 successive 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.
CAUTION! A significant discrepancy is noted between the experimentally determined (33 kDa) vs. expected (60 kDa) molecular weights. Experimental temperature: UNKNOWN. X-ray exposure time: UNKNOWN. SEC-flow rate: UNKNOWN. |
