| Research Abstract |
Our developed software package for electron crystallography is very powerful and effective to determine three dimensional structures of membrane proteins reconstituted into lipid bilayers including aquaporin-4 and gastric H+,K+-ATPase. Using electron crystallography of two-dimensional crystals, we could elucidate their structures and conformational changes during molecular passages.
