Conformational signatures of 13C chemical shifts in RNA ribose.
The conformational dependence of (13)C chemical shift values of RNA riboses determined by liquid-state NMR spectroscopy was evaluated using data deposited for RNA structures in the RCSD and BMRB data bases. Results derived support the applicability of the canonical coordinates approach of Rossi and Harbison (J Magn Reson 151:1-8, 2001) in liquid-state NMR to assess the sugar pucker of ribose units in RNA.
