31P-NMR analysis of the B to Z transition in double-stranded (dC-dG)3 and (dC-dG)4 in high salt solution.

abstract：:Prokaryotic genomic DNA is generally negatively supercoiled in vivo. Many regulatory processes, including the initiation of transcription, are known to depend on the superhelical state of the DNA substrate. The stresses induced within DNA by negative superhelicity can destabilize the DNA duplex at specific sites. Vari...
