Joseph D Walsh,Javier Cabello-Villegas,Yun-Xing Wang,

The periodicity in nucleic acid duplex structures is shown to be correlated to the periodicity in residual dipolar couplings (RDCs) in the form of an "RDC wave". This "RDC wave" is characteristic of the alignment of the duplex in the magnetic field, and hence fitting of the data allows the duplex global orientation (, Phi) to be extracted. Further, because the "RDC wave" is fit as a data set of a corresponding secondary structure element, the degeneracy problem is greatly reduced. Consequently, with the global orientation (, Phi) determined, local bond vector conformations are defined. The fit is demonstrated in the examples of the imino RDCs of the negative regulator of splicing RNA fragment (NRS23) and for the C1'H1' RDCs of the Dickerson dodecamer.
