Abstract
Poly(dG-Me5dC) is known to exhibit a B----Z transition in the presence of very high concentrations of NaCl. For the first time, we report the presence of a Z-structure in sodium concentrations as low as 0.5 mM. A novel Z in equilibrium B in equilibrium Z transition is observed as the salt concentration is gradually increased. The role of water structure in B to Z transitions is discussed.
摘要
已知聚（dG-Me5dC）在极高浓度的氯化钠存在下会发生B向Z的转变。我们首次报道在低至0.5 mM的钠浓度下存在Z结构。随着盐浓度逐渐增加，观察到一种新颖的B态与Z态平衡转变中的Z态。讨论了水结构在B向Z转变中的作用。
