The combination of small-angle X-ray solution scattering (SAXS) experiments and molecular dynamics (MD) simulations is now becoming a powerful tool to study protein dynamics in solution at an atomic resolution. We have developed a method called MD-SAXS, in which this combination is used with explicit evaluation of X-ray scattering from water molecules hydrating protein molecules. This method offers a link between low-resolution structural information from SAXS and the three-dimensional high-resolution structure. The study using MD-SAXS method revealed the importance of intrinsic dynamics of DNA-binding protein EcoO109I in its function.
