Outline of Final Research Achievements

In this study, we investigated the in situ and real-time laser trapping-induced crystallization of proteins. We revealed that (1) the microbubble interface is useful for laser-induced crystallization of protein molecules, (2) it is possible to control the time and space of crystal formation by introducing a single shot of pulsed laser light as an external perturbation into the high concentration region formed by the trapping laser light, (3) the anisotropic orientation and arrangement of protein molecules under the trapping laser light irradiation can be clarified in detail. We also clarified the details of the anisotropic orientation and arrangement of protein molecules under trapping laser irradiation, and it is possible to perform in situ and real-time laser trapping-induced crystallization of spatio-temporally controlled proteins by controlling molecular orientation.

Academic Significance and Societal Importance of the Research Achievements

タンパク質の立体構造を高精度に決定するためには高品質な単結晶が必要不可欠であるが,タンパク質の結晶作製は旧態依然とした試行錯誤的な方法や運に依存している。結晶化スクリーニングに要する結晶化時間の短縮と結晶形成率の高効率化が可能な新規結晶作製手法の開発が必要とされているがそのような手法は未だない。本研究成果はレーザー捕捉法を利活用することでこれまで誰も為し得なかった短時間、in-situかつリアルタイムなタンパク結晶化を可能とするものであり,学術的にも産業・興行的にも意義が大きい。
