Small-angle Scattering and Neutron Spin Echo on Biomolecules

Abstract

To elucidate, predict, and control the biological functions of proteins, it is important to clarify their solution structure and dynamics. Small-angle scattering is one of effective methods for examining the changes in their structures and dynamics due to their binding with target molecules under physiological conditions, although the spatial resolution of the structure revealed by this method is lower than that by crystallographic technique, which provides structural information at atomic resolution. In addition, neutron spin echo is the only technique that can measure the conformational dynamics of proteins in the Q-region, which is covered by small-angle scattering. In this paper, we will introduce some of our recent studies using small-angle scattering and neutron spin echo.
