Statistics Calculated for Selected Chemical Shifts from Atoms in the 4 Common RNA Nucleotides


BMRB Entries not included in the calculations for this table contained chemical shifts outside six standard deviations from the mean calculated for the full BMRB database. This criterium was used to eliminate from the calculations chemical shifts from entries where non-standard chemical shift referencing was used. Of the 78890 possible chemical shifts in the BMRB database, 50137 were included in calculating this table.

In the table, the highlighted residue codes provide a link to a gif image of the nucleotide with its atom nomenclature.
