Outline of Final Research Achievements

Protein A is oftein used for preparation of immunoglobulins. However, its conformation is solution has not known. We have used X-ray solution scattering method for obtaining the conformation of protein A and its derivatives.
Results are also compared with the structure predicted by molecular dynamics, which gives the very good coincidence. This result suggests the protein A takes the relaxed conformaton without the stress.
We have also done X-ray solution scattering study on the complex of protein A and Fc fragment of Immunoglobulin, and successfully obtained the scattering profile of the complex. Further analysis should be done.
