Brookhaven Protein Data Bank. A database and format of files which describe the 3D structure of a protein or nucleic acid, as determined by X-ray crystallography or nuclear magnetic resonance (NMR) imaging. The molecules described by the files are usually viewed locally by dedicated software, but can sometimes be visualised on the world wide web.
chemical/x-pdb -- It started as the Protein Databank format and grew from there. It is currently the preferred format because viewers are available for all platforms.
protein data bank PDB is an archive of experimentally-determined three-dimensional structures ( Brookhaven nat. Labs or EBI). Domain families represented in SMART and in the PDB are annotated as being of known structure; links are provided in SMART to the PDB via PDBsum and MMDB. PDBsum links can be used to access a variety of sequence-based and structure-based tools, whereas MMDB provides access to literature information and structure similarities.
