The X-ray crystallographic study of the conformation of Z-DNA which bound to polyamine for the minor groove at room temperature and low temperature.
We succeeded in x-ray crystal analysis of d(CG)3 with N1-{2-[(2-amino-ethylamino)-ethylamino]-ethyl}-ethane-1,2-diamine complex at three conditions (1: room temperature 2: low temperature 3: highly salt condition). At room temperature two polyamines took extended form and bound to minor groove of d(CG)3, at low temperature two polyamines took U-shape form and lied in minor groove of d(CG)3, at highly salt condition two polyamines took fishhook form and one polyamine lied in upper side of minor groove and the other polyamine lied in down side of minor groove of d(CG)3.
