Flipping of cloned d(pCpG)n.d(pCpG)n DNA sequences from right- to left-handed helical structure by salt, Co(III), or negative supercoiling.
Negative supercoiling of plasmid DNAs containing 24--42 base pairs of alternating d(pCpG) inserts is shown to cause the flipping of the helical hand of the inserts from right to left under physiological conditions. For a negatively supercoiled DNA with a fixed linking number, this flipping reduces i...
