Research Abstract

About 70% of currently used medical drugs are said to be targeted to membrane proteins. Because of this, the knowledge about the 3D structure of these proteins is indispensable for the development of new drugs. However, the structures of only a few of the membrane proteins have been solved, because it is generally difficult to obtain crystals of these proteins, which are indispensable for the standard procedure of structure determination. This study is conducted to develop the principles needed to determine the structure of these proteins without making crystals, by applying the technique of X-ray holography.
