[Effect of ionization of system components on the interaction of polyuridylic acid with adenosine. Deprotonation of the polynucleotide].
The interdependence of complex formation and poly(U) deprotonation in the poly(U)-adenosine system has been studied by UV spectroscopy, titration and equilibrium dialysis techniques. Evidence is presented on the formation of an intermediate, probably double helical, structure in the course of A-2 poly(U) dissociation at alkaline pH.
