Zinc Z-DNA.

Abstract

Circular dichroism spectra of poly(dG-dC) in the presence of some zinc complexes exhibit the characteristic inversion associated with the formation of a left handed helix. The transition of B to Z DNA is cooperative and slow. The concentration of zinc complex at the mid point of the transition is strongly dependent upon the nature of the ligand bound to zinc. The most efficient species is one with a tetradentate amine for which the mid point is observed at a zinc:nucleotide ratio of 1:24. 31P spectra of one of these complexes confirm the presence of a left handed helix.
