The BMRB database contains NMR chemical shifts derived from proteins and peptides, reference data, amino acid sequence information, and data describing the source of the protein and the conditions used to study the protein. In constructing the database, proteins and larger peptides have been given priority. Shift assignments for hemes, cofactors, and substrates of a protein are also included, when they are reported as part of a complex. The July 31, 1995 release of the database contains over 94,000 unique chemical shifts including more than 6,000 13C shifts and 4,000 15N shifts. An additional 30,000 stereospecific ambiguous chemical shifts are available. The present form of the database is described in the publication "A Relational Database for Sequence-Specific Protein NMR Data", B.R. Seavey, E.A. Farr, W.M. Westler, and J.L. Markley, J. Biomol. NMR 1, 217-236 (1991).
Work is in progress to enlarge the scope of the database to contain a majority of the quantitative structural, kinetic, and thermodynamic data produced by NMR studies of proteins, peptides, and nucleic acids. Included will be chemical shifts, coupling constants, H-exchange rates and protection factors, atomic relaxation parameters, molecular correlation times, reaction rates, pKa values, H-fractionation factors, rotomer populations, and thermodynamic values from molecular interaction and chemical reaction studies. Atomic coordinate data will be included through a collaboration with the Protein Data Bank (PDB) and links between relevant entries in both BMRB and PDB. Additional information about the experiments and procedures used to derive the data also will be available.
Soon we will be depositing data to the BMRB, just as we deposit our structures at the PDB.

Search for your protein via one of the options on the NMR browser page and download what you need.
Another, very efficient way of getting data is via NIH. Go to WWW Database Gateway to BioMagResBank at NIH. From there, you can query the database for proteins and authors.
