Transcript of The Protein Data Bank (PDB) & PDB Files

  • The Protein Data Bank (PDB) & PDB FilesLesson Date: 09/01/04 WCreated by: Angela M. Amoia 08/20/04

  • Lesson ObjectivesRecall what the PDB is and what is storesRecall what a PDB file is and what its contents stand forSummarize two (2) ways to obtain PDB files associated with an articleSummarize how to find articles associated with a PDB file

  • Protein Data Bank (PDB)Single World Wide databaseStores atomic coordinates of protein & nucleic acid structures knownCoordinates determined by:X-Ray Crystallography NMRAssigned PDB ID or accession number4 characters; ex. 1ANG

  • PDB File (.pdb)Text file, viewed/modified in editor (TextPad)a.k.a. structure fileContains position of every atom in the file as well as some information about the structureHolds all the information needed to reconstruct a 3D model of a molecule view in RASMOL or DeepViewAt first, contents are intimidating! But they are actually quite simple documents!

  • Contents of PDB fileGeneral information about the molecule: name, ligands, sequence, references to journal articles, etc.

  • Contents of PDB fileInformation about each atom in the structure: arranged in sequence- first amino acid first, last amino acid last

  • How can I obtain PDB files associated with an article?

    Link from PubMed article to associated structures in PDB

    Directly from PDB using the PDB accession number acquired from a paper

  • If I already have a structure in mind, how can I find articles associated with it?

    Use the PDB search engine and link from the PDB to PubMed
