We clarified stabilization mechanism of left-handed Z-DNA by X-ray crystal structure analysis. I was able to achieve it by burying big minor groove of Z-DNA because metal ion and polyamine connected it to minor groove of Z-DNA. On that occasion I understood that an electric charge and length of polyamine gave big influence to a combination brain very much. I succeeded in crystallization of Z-DNA of a long chain, X-ray crystal structure analysis by examining these combination ability.
