The Re-referenced Protein Chemical shift Database (RefDB) is a NMR spectroscopy database of carefully corrected or re-referenced chemical shifts derived from the BioMagResBank (BMRB) (Fig. 1). The database was assembled by using a structure-based chemical shift calculation program (called SHIFTX) to calculate expected protein (1)H (13)C and (15)N chemical shifts from X-ray or NMR coordinate data of previously assigned proteins reported in the BMRB.
