The neutron associate elastic scattering device installed in large strength pulse neutron J-PARC is effective for the analysis of the protein dynamics of the pico second - nanosecond. It will show the importance of the QENS experiment of the protein using J-PARC to clarify how the dynamics of the space scale are related with cooperative dynamics of the whole protein affecting creature function expression then. On the other hand, for the structural biology to discuss a function based on a tertiary structure, it is difficult to relate a function to structure dynamics only from QENS spectrum. It is effective to quote molecular simulation so that structure discusses the information of dynamics to relate a function to structure scientifically. I suggest that I visualize the hierarchical structure of protein dynamics in atom resolving power by the MD-Neutron method which fused by a neutron dispersion experiment and molecules simulation while utilizing various technique of the structural biology in this announcement from different angles. In addition, about MurD which is multi-domain protein, I discuss a function of the protein from the dynamic structure that a couple did between the hierarchies of the scale between the different space-time.
