Formation of Z-DNA in negatively supercoiled plasmids is sensitive to small changes in salt concentration within the physiological range.

Negative supercoiling of the plasmid pBR322 with or without an insert of (dG-dC)n induces the formation of Z-DNA as measured by the binding of antibodies specific for Z-DNA. Increasing the concentration of Na+ (or K+) is shown to inhibit the B to Z-DNA conversion. This may be due to the effect of th...
