Synchrotron SAXS data from solutions of Bovine β Cardiac Myosin S1 fragment (Myosin-7) MgADP.VO4+OM in 10 mM HEPES, 50 mM NaCl, 1 mM NaN3, 2.5 mM MgCl2, 2 mM ADP, 1 mM TCEP, pH 7.5 were collected on the SWING beam line at SOLEIL (Saint-Aubin, France) using a CCD AVIEX detector at a sample-detector distance of 1.8 m and at a wavelength of λ = 0.10332 nm (I(s) vs s, where s = 4πsinθ/λ and 2θ is the scattering angle). One solute concentration of 4.00 mg/ml was measured. 41 successive 0.500 second frames were collected. The data were normalized to the intensity of the transmitted beam and radially averaged and the scattering of the solvent-blank was subtracted.
