U-box domain-containing protein 44 SASREF MX model

Synchrotron SAXS data from solutions of Armadillo repeat 7-11 from SAUL1 in 50 mM Tris, 250 mM NaCl, pH 9 were collected on the EMBL P12 beam line at the PETRA III storage ring (Hamburg, Germany) using a Pilatus 2M detector at a sample-detector distance of 3 m and at a wavelength of λ = 0.123987 nm (I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). One solute concentration of 2.00 mg/ml was measured at 10°C. 20 successive 0.050 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.

The rigid bodies used for the SASREF MX tetramer model were predicted by I-TASSER.
