Site-specific cleavage of supercoiled DNA by ascorbate/Cu(II).
We have investigated ascorbate/Cu(II) cleavage of double-stranded DNA in the presence and absence of DNA negative torsion. We found that ascorbate/Cu(II) cleavage shows a site-specificity that is dependent on negative torsion and is influenced by the nature of the salt, ionic strength, and pH. This...
