lüll Atomic-scale dynamics inside living cells explored by neutron scattering Jasnin MJ R Soc Interface 2009[Oct]; 6 Suppl 5 (Suppl 5): S611-7Single-particle neutron spectroscopy has contributed important experimental data on molecular dynamics in biological systems. The technique provides information on atomic and molecular motions in macromolecules on the picosecond to the nanosecond time scale, which are essential to biological function. Here, we report on recent neutron measurements performed directly in living cells by using isotope labelling to explore the dynamics of specific cellular components. The paper proposes an integrated view of results on atomic-scale cell water dynamics, internal and global macromolecular motions and solvent isotope effect on macromolecular dynamics. The work established the specific usefulness of the neutron scattering technique to get insight into biologically relevant dynamical features, in particular through comparative measurements. The method developed can now be applied to look for dynamical signatures related to cell characteristics in many different cell types and organelles.|Escherichia coli/*ultrastructure[MESH]|Neutron Diffraction/*methods[MESH]|Subcellular Fractions/*ultrastructure[MESH] |
