Deposition of NMR data is possible via one of the following three deposition systems, which depends on size of biological macromolecule being studied and whether its coordinates are included.

Deposition system Number of residues, Coordinates Archive site
SMSDep The entity is one of a polypeptide with 23 or fewer residues,
a polynucleotide with 3 or fewer residues,
a polysaccharide with 3 or fewer residues,
and a natural product.
Coordinates is required.
NMR data: BMRB
Coordinates: BMRB
OneDep The entity is larger than the SMSDep conditions above.
Coordinates is required.
NMR data: BMRB
Coordinates: PDB
BMRBdep (BMRB Only) No limitation on the molecular assembly.
Coordinates should not be included.

Small peptide less than 24 residues that have proven to be biologically important can be accepted by PDB (OneDep). Acceptance of the primary citation is also required to release the PDB entry. If conditions for the PDB acception are not certain, please contact PDBj bioculator before deposition.

What types of structure can be deposited to PDB?

Biomolecular polymers including polypeptides, polynucleotides, polysaccharides, and their complexes that meet the following criteria are accepted:

Crystal structures of peptides with fewer than 24 residues within any polymer chain that do not meet criteria 1, 2, or 3 can be deposited at Cambridge Crystallographic Data Centre (CCDC).

NMR structures of such molecules can be submitted to SMSDep system.

Smaller oligonucleotides (dinucleotides and trinucleotides) can be deposited at Nucleic Acid Database (NDB).

Molecules that do not conform to these guidelines but have been previously deposited in PDB will not be removed.
