PDB Downloader (Source)

StreamableVernalis PDB Connector KNIME nodes package version 1.30.2.v202106181332 by Vernalis (R&D), UK

This node, and the corresponding manipulator node, allows the downloading of structure and sequence files from the RCSB PDB . The formats supported are:
  • PDB
  • mmCIF
  • Structure Factors
  • FASTA Format Sequence
  • NMR Restraints
  • NMR Restraints v2
  • NMR Chemical Shifts
PDB files are cast as PDB cells, and PDBML as XML cells. No checking the the structure IDs is carried out - invalid IDs will return cells containing missing values. WARNING - the PDBML option can result in very large tables!

This node was developed by Vernalis (Cambridge, UK) . For feedback and more information, please contact knime@vernalis.com
