New RCSB PDB Website Provides Tools and Resources for Studying Biological Macromolecules

At the very end of 2005, the RCSB PDB moved the updated version of the resource into production. The website and database at have been enhanced and revised to provide a powerful portal for studying the structures of biological macromolecules and their relationships to sequence, function, and disease.

The RCSB PDB thanks everyone who has contributed to the development of this new resource since testing began in July 2004. Questions about the transition to this site not addressed in the FAQ should be sent to

The new database utilizes PDB data that has been remediated and standardized for better searches and reports. Other features include improved ligand searching, a clear distinction between the reported primary and derived data, and the integration of external data resources (such as SCOP, CATH and chromosome location). A permanent search tab offers different ways of accessing the database, including a new method for "browsing" through structures grouped in categories (related to, for example, disease, molecular function, biochemical process, or cellular location).

Navigation of the website has been enhanced to keep the resources and tools related to structural genomics, education, and software within easy reach. A searchable help system with a glossary and user guide provides detailed information for accessing the website, database, and understanding PDB data. A narrated presentation (in Flash) guides users through searching, navigating, generating reports, visualizing structures, and browsing PDB data on the new site. The structural genomics portal is enriched with target summary reports for centers worldwide, databases that track the progress of protein studies (TargetDB and PepcDB), and a tool to explore the distributions of functions found among structural genomics structures, PDB structures, genomes, and homology models.
