Synchrotron SAXS data from solutions of cytochrome c nitrite reductase in Tris-borate buffer, pH 8.5 were collected on the EMBL X33 beam line at DORIS III (DESY, Hamburg, Germany) using a MAR 345 Image Plate detector at a sample-detector distance of 2.7 m and at a wavelength of λ = 0.154 nm (I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle). One solute concentration of 1.50 mg/ml was measured at 20°C. One 120 second frame was collected. The data were normalized to the intensity of the transmitted beam and radially averaged; the scattering of the solvent-blank was subtracted.
