Question
Which database serves as a repository for protein 3D structures, including those relevant to immunology? Select one: a. NCBI b. PDB (Protein Data Bank) c. IEDB (Immune Epitope Database) d. GenBank
Solution
The correct answer is b. PDB (Protein Data Bank). The Protein Data Bank (PDB) is a database for the three-dimensional structural data of large biological molecules, such as proteins and nucleic acids. The data, typically obtained by X-ray crystallography, NMR spectroscopy, or, increasingly, cryo-electron microscopy, and submitted by biologists and biochemists from around the world, are freely accessible on the Internet via the websites of its member organisations (PDBe, PDBj, and RCSB). The PDB is overseen by an organization called the Worldwide Protein Data Bank, wwPDB.
