RefDB
收藏资源简介:
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.
重新校准蛋白质化学位移数据库(Re-referenced Protein Chemical shift Database,RefDB)是一套源自生物磁共振数据库(BioMagRes Bank,以下简称BMRB),并经过精心校正或重新校准的化学位移数据库。其构建流程为:借助SHIFTX软件,利用X射线或核磁共振(Nuclear Magnetic Resonance)坐标数据预测蛋白质的1H、13C及15N化学位移,随后通过SHIFTCOR软件将上述预测结果与BMRB中报道的实测化学位移进行比对。RefDB可为核磁共振波谱学家提供标准化的化学位移资源,以支持其推导或计算肽类与蛋白质中的化学位移趋势。
