B-Z transition in poly(dG-dC).poly(dG-dC) in the presence of formaldehyde amino derivatives.
It was shown by circular dichroism that the B-Z transition of poly(dG-dC).poly(dG-dC) in high NaCl concentrations occurred more rapidly in the presence of formaldehyde and Tris. The product of formaldehyde and glycine interaction induces changes in the poly(dG-dC).poly(dG-dC) CD spectral characteristics of a 'B-like' conformation. It is supposed that the B-Z transition occurs without large-scale hydrogen bond breakage.
