Research Abstract

The final goal of this project was to obtain the crystal structure of LINE-EN : DNA to reveal how LINE-EN to bind to DNA and cleave it, but it was not completed. During the optimization for crystallization, I found that LINE-EN would form a dimer in solution, and that EN alone is not enough to make the stable complex with DNA and necessary a Myb-like domain located just downstream of EN.
