The Biological Magnetic Resonance Data Bank (BioMagResBank or BMRB) is an open access repository of nuclear magnetic resonance (NMR) spectroscopic data from peptides, proteins, nucleic acids and other biologically relevant molecules.

The BMRB is part of the Research Collaboratory for Structural Bioinformatics[2] and, since 2006, it is a partner in the Worldwide Protein Data Bank (wwPDB).

[4] The bulk of the data deposited at the BMRB consists of over 11,900 entries containing 1H, 13C, 15N and 31P assigned chemical shifts and coupling constants of peptides, proteins and nucleic acids.

[1] The BMRB hosts a database containing NMR spectral data from hundreds of metabolomic compounds.

The BMRB provides a collection of NMR statistical data, including chemical shift distributions for individual atoms in amino acids, ribonucleotides and deoxyribonucleotides.

[7] The BMRB Query Grid Interface,[8] allows to search the database by molecule type (peptide, protein, DNA, RNA, etc.

[13] The site also contains an NMR-STAR template generator which produces formatted tables where NMR data can be entered.

[16] Once the data is deposited, it is checked for completeness, consistency and annotated, links to other databases are added and a BMRB accession number is generated.
