Zaccai et al. proposed to build up a neutron Dynamics Data Bank which would be populated with dynamical data of biological macromolecules measured with different techniques, neutron scattering, MD simulations and NMR. The aim is to concentrate the obtained data which should result in a global picture of the dynamics of biomolecules. However, there still exist large gaps between simulations and experiments. It is the goal of the recently started PhD project of D. Zeller to find out how quantitatively MD simulations can reproduce the trend of experimental data over a range of divers systems and instruments under various conditions like temperature, hydration, pH, etc. To start this analysis a proposal is pending at the ILL to measure bovine alpha-Lactalbumin at different hydration levels. We want to add measurements at IRIS where we can obtain data over a broader momentum transfer range Q.
