Data validation


There are no models related to this curve.

Synchrotron SAXS data from solutions of N-Myc proto-oncogene residues 1-69 in complex with Aurora kinase A mutant C290A:C393A in 20mM HEPES, 150mM NaCl, 5mM MgCl2, 3% v/v glycerol, 2mM TCEP, pH 7.5 were collected on the EMBL P12 beam line at the PETRA III storage ring (DESY; Hamburg, Germany) using a Pilatus 6M detector (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 column . The data were normalized to the intensity of the transmitted beam and radially averaged; the scattering of the solvent-blank was subtracted.

Synchrotron SAXS data from solutions of the N-Myc proto-oncogen protein (residues 1-69) in complex with the kinase domain of Aurora kinase A (residues 122-403, containing a C290A:C393A double mutation) was collected in 20mM HEPES, 150mM NaCl, 5mM MgCl2, 3% v/v glycerol, 2mM TCEP, pH 7.5 on the EMBL P12 beam line at PETRA III (DESY, Hamburg, Germany) using a Pilatus 6M detector at a sample-detector distance of 3 m and a wavelength of λ = 0.124 nm (I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). In-line size-exclusion chromatography (SEC) SAXS was employed by injecting 90.00 μl sample of 10 mg/ml onto a GE Superdex 75 Increase 10/300 column with a flow rate of 0.70 ml/min at 20°C. 2100 successive 1 second frames were collected. Buffer subtraction was done using CHROMIXS and data analysis was done using the ATSAS suite.
