| Outline of Final Research Achievements |
Due to the remarkable progress of X-ray crystal structure analysis, structure determination from micro protien crystals has been reported. These results are dramatically changing the common sense of protien crystallization which requires a long time, a large quantity and high quality of protein samples. One challenge using this technique is to determine protien structures with microcrystals formed spontaneously in cells. Natural systems utilize intracellular crystallization reactions for purification and storage of protein synthesized in vivo. In this study, we succeeded in the creation of protein crystals with pore spaces as intracellular templates as an innovative crystallization method for rapid crystal structure analysis. In addition, we succeeded in accumulating the target protein simultaneously produced in the crystal.
