Submission of NMR data or structures to the BRMB database is done via one of two web pages depending on the number of residues your biopolymer possesses. Biomolecules with less than 23 residues can be submitted using the SMSDep link, biomolecules with a greater number of residues should use the ADIT-NMR link. SMSDep is for archiving the NMR structural information of biomolecules that fall outside the guidelines of the Protein Data Bank. Please refer to the table below.

PDB policy for acceptable structures has been updated

All biological relevant small peptides are acceptable at PDB now. When the requirement by the PDB policy is met , Small Molecule Structures concerned with biology can be deposited at PDB via ADIT-NMR.
Before depositing your data, please contact PDBj Deposition staff.

What types of structure can be deposited to the 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 the Cambridge Crystallographic Data Centre (CCDC, http://www.ccdc.cam.ac.uk/products/csd/deposit/).

NMR structures of such molecules can be submitted to Biological Magnetic Resonance Data Bank (BMRB) through the Small Molecule Structure Deposition (SMSdep, http://smsdep.protein.osaka-u.ac.jp/bmrb-adit/) system.

Smaller oligonucleotides (dinucleotides and trinucleotides) can be deposited at the Nucleic Acid Database (NDB, http://ndbserver.rutgers.edu).

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