2. worldwide Protein Data Bank (wwPDB) Consists of four sites RCSB (USA), PDB-j (Japan) BMRB (USA) and PDBe. Single repository of macromolecular structures. Started in 1971 and now ~65,000 entries, adding ~200 new entries/week. Deposited by experimentalists and contents is freely available. The format of the archive is flat-files with fixed line format, although an improved flat-file format (mmCIF) and XML are also available.

3. Protein Databank in Europe (PDBe) group Is one of the four sites around the world that where 3D structures may be deposited. Provides stable and clean repository of macromolecular structure data. Has services that allow users to access, search and retrieve structural data from a single web access point.

5. Deposition via AutoDep4 (http://www.ebi.ac.uk/pdbe-xdep/autodep) Closely collaborate with the other wwPDB members for a single unified archive.. Depositions via EMDEP (http://www.ebi.ac.uk/pdbe-emdep/emdep) Depositions started June 2002 Depositions and Curation

6. Validation of Structures Authentication of source That the protein is from human and not rabbit, for example ! Authentication of structure Comparison of structure against raw data. Geometry and Stereochemistry. Provide results back to depositor. Validation of correct methodology used Whether X-Ray, NMR or EM. Conformity to standards Follows PDB format specifications Error checks Consistency checks - to identify simple typos Homo sapiens and not Homo sapien (single human?). Outlier detection - to identify suspect records

8. Disadvantages of Flat files… Macromolecular structures are very complex. Existing PDB format is incapable of fully describing few existing structures also. Format is not readily extensible, to cope, for example, with structural genomics data. Historical archive is non-uniform and poorly populated. Search and retrieval of flat files is difficult and/or inaccurate.

11. Some Implementation Issues  The PDBe database is large and complex:  ~61,000 PDB entries  Cross-referenced against SwissProt, PubMed etc.  Making data accessible without adding additional complexity.  Tools for different categories of end-user  Simple – biobar  Intermediate - PDBelite  Advanced – PDBepro  New - PDBeView

12. biobar A toolbar search application for Mozilla/Netscape or firefox browsers http://biobar.mozdev.org/ Simple and quick retrieval of data from PDBe and 45 other Databases

13. PDBelite A simple form-based query system to search the PDBe Databases

14. PDBelite Search Results

15. Features of Search Interface Strengths: simple, easy to use form allows multiple search fields to be combined relatively fast, despite performing quite complex SQL queries Weaknesses: not exposing the power of a relational database limited logical operators between search fields: "name" AND "title" AND "keyword“  "name" OR "title" OR "keyword“  ( "name" OR "title" ) AND NOT "keyword" the search form is defined by the authors of the search system, not the author of a query
