A novel structural transition in poly(dG-Me5dC):Z in equilibrium B in equilibrium Z.

P K Latha, S K Brahmachari.   

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.
