Very good agreement between the experimental results and computed data (based on the above kinetic reaction model) was found for the B, Z, and coil proportions.
Characterization of DNA structures by infrared spectroscopy: double helical forms of poly(dG-dC)•poly(dG-dC), poly(dD8G-dC)•poly(dD8G-dC), and poly(dG-dm5C)•poly(dG-dm5C)

A set of ir bands characteristic of DNA conformations, which can be used in studies of interactions with this polynucleotide and to identify the left handed Z conformation in more complex systems, is proposed.

The IR spectra of Ni2+-poly[d(A-T)] films reflect a Z-type structure, favored by the high polynucleotide concentration, by the low water content of the films, and by specific interactions of the transition metal ions with the purine bases stabilized in a syn conformation.

Based on the IR spectroscopy results, an explanation is proposed for the different efficiencies of these various ions to induce the B----Z transition.

A new simple method is proposed to evaluate the amount of A or B forms of DNA when both structures are present and it is found that the B leads to A transition is fully inhibited when only one molecule of H2B or H3 histone is bound per about three or four turns of DNA helix.

Infrared spectroscopic studies demonstrate the ability of poly[d(A-C)].poly[ d(G-T)] to adopt a Z-type conformation and the importance of specific binding of Ni2+ ions on the N7 site of purines in the stabilization of the Z form is discussed.

The results suggest that d(A-T-G-G)cisPt can adopt two different conformations depending on the temperature, and the enthalpy for the transition between the high and low temperature conformations is about 84 kJ/mol.
Proton NMR and circular dichroism studies of the B and Z conformations of the self-complementary deoxyhexanucleotide d(m5C-G-C-G-m5C-G): mechanism of the Z-B-coil transitions.

From proton line-width measurements under various experimental conditions, it was shown that Z exchanges only with B, while the latter also exchanges with the single-stranded form (S): Z in equilibrium B in equilibrium S.
