| Outline of Final Research Achievements |
New methodology for small-angle neutron scattering corresponding to solvent contrast variation and deuteration labeling techniques has been developed and then structural investigation of protein state in an aqueous solution was performed. At first, the simulation codes were made to calculate a scattering function from PDB data considering about two techniques and a code was also made to analyze dynamical state of protein with domains with Mote Carlo algorithm. It was confirmed to be available to analyze the static and dynamical states by using them. with real protein systems: βB2-Crystatallin and proteasome activator 28. In addition, it was succeeded to prepare for 75% deuteration protein which can be matched out in 100% D2O solution.
