Coordinate Files

  • na-biol. Coordinate files (PDB format) for one biological assembly of nucleic acid-containing structures determined by x-ray crystallography.
  • na-deposited. Coordinate files (PDB format) for the asymmetric unit of nucleic acid-containing structures determined by x-ray crystallography. The chirality has been corrected for these structures.
  • na-mmcif. Coordinate files (mmCIF format) for the asymmetric unit of nucleic acid-containing structures determined by x-ray crystallography in mmCIF format.
  • na-nmr. Copies of the coordinate files released by the PDB for nucleic acid-containing structures determined by NMR.
  • na-nmr-mmcif. Coordinate files (mmCIF format) for nucleic acid-containing structures determined by NMR in mmCIF format.
  • na-obsolete. Coordinate files (PDB format) for structures that have been obsolete or replaced.
  • NDB only. Files for structures that are present only in NDB and not in PDB.
