NMR Structure Determination for Oligonucleotides.
Current protocols in nucleic acid chemistry(2018)
Abstract
NMR spectroscopy is a versatile tool for determining the structure and dynamics of nucleic acids under solution conditions. In this unit, we provide an overview and detail of the experiments and methods used in our laboratory to determine the structure of oligonucleotides at natural abundance, thus limiting our approach to H, C, and P NMR techniques. Isotopic labeling is heavily used in RNA NMR studies, however, labeling of DNA is still less common and, if modified nucleotides are investigated, is exceptionally expensive or not feasible. Each method described here is extensively documented and annotated with tips and observations to facilitate their application. Sections are devoted to sample preparation, NMR experiments and setup, resonance assignment, structure generation protocols, evaluation, tips that may be useful, and software sources. © 2018 by John Wiley & Sons, Inc.
