Efficient detection of hydrogen bonds in dynamic regions of RNA by sensitivity-optimized NMR pulse sequences

Angew Chem Int Ed Engl. 2013 Sep 27;52(40):10487-90. doi: 10.1002/anie.201304391. Epub 2013 Aug 14.


Improved Sensitivity: Efficient NMR experiments are presented for determining the secondary structure in large and dynamic RNAs using J-couplings across hydrogen bonds. The experiments provide up to eight-fold improved sensitivity and thus enable detection of base pairs in dynamic regions even in large RNAs.

Keywords: NMR spectroscopy; RNA dynamics; RNA secondary structure; base pairs; hydrogen bonds.
