The Biological Magnetic Resonance Data Bank (BMRB) contains NMR chemical shift
depositions for over 200 RNAs and RNA-containing complexes. We have analyzed the
(1)H NMR and (13)C chemical shifts reported for non-exchangeable protons of 187
of these RNAs. Software was developed that downloads BMRB datasets and
corresponding PDB structure files, and then generates residue-specific attributes
based on the calculated secondary structure. Attributes represent properties
present in each sequential stretch of five adjacent residues and include
variables such as nucleotide type, base-pair presence and type, and tetraloop
types. Attributes and (1)H and (13)C NMR chemical shifts of the central
nucleotide are then used as input to train a predictive model using support
vector regression. These models can then be used to predict shifts for new
sequences. The new software tools, available as stand-alone scripts or integrated
into the NMR visualization and analysis program NMRViewJ, should facilitate NMR
assignment and/or validation of RNA (1)H and (13)C chemical shifts. In addition,
our findings enabled the re-calibration a ring-current shift model using
published NMR chemical shifts and high-resolution X-ray structural data as
guides.
