RefDB

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.

重校准蛋白质化学位移数据库（Re-referenced Protein Chemical shift Database，RefDB）是一个经精心校正或重新校准的化学位移数据库，其数据源自生物磁共振库（BioMagResBank，BMRB）。该数据库的构建流程为：通过SHIFTX工具，基于X射线或核磁共振（NMR）坐标数据预测蛋白质的1H、13C及15N化学位移，随后借助SHIFTCOR工具将上述预测结果与BMRB中记录的实测位移进行比对。RefDB 为核磁共振光谱学家提供了标准化的化学位移资源，可供其推导或计算肽类与蛋白质的化学位移变化趋势。
