The Re-referenced Protein Chemical shift Database (RefDB) is a database of carefully corrected or re-referenced chemical shifts, derived from the BioMagRes Bank. The process involves predicting protein 1H, 13C and 15N chemical shifts using X-ray or NMR coordinate data via SHIFTX and then comparing those predictions to the observed shifts reported in the BMRB (via SHIFTCOR). RefDB provides a standard chemical shift resource for NMR spectroscopists, wishing to derive or compute chemical shift trends in peptides and proteins.
