Structure of Poly (U)•Poly (A)•Poly (U)

Journal of Biomolecular Structure and Dynamics, 2000
The molecular structure of poly (U).poly (A).poly (U) has been determined and refined using the continuous x-ray intensity data on layer lines in the diffraction pattern obtained from an oriented fiber of the RNA. The final R-value for the preferred structure is 0.24, far lower than that for the plausible alternatives.

The Structure of Triple Helical Poly(U)·Poly(A)·Poly(U) Studied by Raman Spectroscopy

Journal of Biomolecular Structure and Dynamics, 1984
Using Raman spectroscopy, we examined the ribose-phosphate backbone conformation, the hydrogen bonding interactions, and the stacking of the bases of the poly(U).poly(A).poly(U) triple helix. We compared the Raman spectra of poly(U).poly(A).poly(U) in H2O and D2O with those obtained for single-stranded poly(A) and poly(U) and for double-stranded poly(A)

Poly A-Poly U: An Updated Review

Biopolymers, 1990
Poly A:Poly U is a biological response modifier consisting of the twin-chain RNA polymers polyadenylic and polyuridylic acids forming a synthetic polyribonucleotide complex. The compound is endowed with a variety of immunopharmacological activities on both the humoral and cellular components of the immune response and exhibits antitumor effects.

The low temperature reaction of poly U and poly A

Experientia, 1967
Es wurde die Temperaturabhangigkeit der Wechselwirkung von Polyriboadenylicsaure mit Polyriboridylicsaure viskosometrisch untersucht. Zeitund Temperaturabhangigkeiten der Viskose deuten an, dass der Zustand der Polymer-Organisation die Reaktion beeinflusst.

Mg2+ ion effect on conformational equilibrium of poly A · 2 poly U and poly A poly U in aqueous solutions

International Journal of Biological Macromolecules, 2003
Differential UV spectroscopy and thermal denaturation were used to study the Mg(2+) ion effect on the conformational equilibrium in poly A.2 poly U (A2U) and poly A . poly U (AU) solutions at low (0.01 M Na(+)) and high (0.1 M Na(+)) ionic strengths.
