Abstract
Fourteen OsO4 complexes with different ligands were tested as probes of DNA structure. Of these complexes, only OsO4-2,2'-bipyridine (Os-bipy), OsO4-bathophenanthrolinedisulfonic acid (Os-bpds) and OsO4-N,N,N',N'-tetramethylenediamine (Os-TMEN) site-specifically modified the ColE1 cruciform in a supercoiled plasmid pColIR215 at millimolar concentrations. Os-bipy, Os-bpds and Os-TMEN also displayed site-specific modification of the B-Z junctions in the supercoiled plasmid pRW751 containing (dC-dG)n inserts.Entities:
