Research Abstract

I tried to make a large crystal of a membrane protein, bacteriorhodopsin, which is enough to decide detailed structure including the positions of hydrogen atoms. But I could not make a large crystal during this research period. On the other hand, it has been revealed that structural transition of lipids effects to the crystallization of bacteriorhodopsin, which is an important aspect of crystallization mechanism of membrane proteins in lipids.
