The sequence (dC-dA)n X (dG-dT)n forms left-handed Z-DNA in negatively supercoiled plasmids.
Z-DNA-specific antibodies have been used to demonstrate the formation of left-handed Z-DNA in sequences of (dC-dA)32 X (dG-dT)32 in negatively supercoiled plasmids. Z-DNA was found to form at physiological negative superhelical densities (sigma = -0.05) in the absence of high salt concentration or c...
