Synchrotron SAXS data from solutions of Tissue Transglutaminase + 2% DMSO in 20 mM HEPES, 100 mM NaCl, 10% glycerol, 1 mM DTT, pH 7.5 were collected on the ID7A1 BioSAXS / HP-Bio Beamline beam line at the Cornell High Energy Synchrotron Source (CHESS) storage ring (Ithaca, NY, USA) using a Eiger 4M detector at a sample-detector distance of 1.6 m and at a wavelength of λ = 0.123 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. 15 successive 5 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.
