Outline of Final Research Achievements |
Salt-free protein crystallization method with centrifugal concentration apparatus has been developed. With this method, nucleation of hen egg-white lysozyme (HEWL) crystals occurs in hyper-concentrated liquid phase obtained by liquid-liquid phase separation during centrifugal concentration processes. We could successfully observed molecular steps on the obtained crystal surface. Three-dimensional structure of lysozyme molecule obtained in this method is significantly different from that obtained by normal salting-out method.
