As a founding member of the Worldwide Protein Data Bank (wwPDB) collaboration, we support scientific research and education by providing the essential Protein Data Bank (PDB) archive of information about the experimentally-determined structures of proteins, nucleic acids, and complex assemblies. The wwPDB organization ensures that the PDB is freely and publicly available to the global community. Members host deposition, annotation, and distribution centers for PDB data and collaborate on a variety of projects and outreach efforts, including developing tools and processes for validating and remediating structural data.
The Research Collaboratory for Structural Bioinformatics (RCSB) PDB, a collaboration between Rutgers and the University of California, San Diego, RCSB PDB maintains the central repository of the PDB archive for the wwPDB, and provides resources that promote a structural view of biology, including a relational database, molecular viewers, structure comparison tools, and educational materials such as the Molecule of the Month series.
The Electron Microscopy Data Bank (EMDB) is a joint effort of the Protein Data Bank in Europe, the RCSB, and National Center for Macromolecular Imaging that provides a global deposition and retrieval network for cryoEM map, model and associated metadata, and a portal for software tools for standardized map format conversion, map, segmentation and model assessment, visualization, and data integration.
In 2008, the PSI-Nature Structural Genomics Knowledgebase (PSI SGKB) was established to turn the products of the Protein Structure Initiative into knowledge that is important for understanding living systems and disease. A single search of the SGKB provides links to 3D structures, pre-built models, annotations, target information, protocols, and access to DNA clones. The site offers an easy way to keep abreast of developments both by the PSI and more generally in the fields of structural genomics and structural biology.
The work on these projects has been informed by our research and studies in structural biology, in particular protein-nucleic acid interactions, binary and ternary complexes with catabolite activating protein (CAP), and nucleic acids. Several studies have been focused on defining the precise molecular interactions involved in transcription activation by CAP. In a project led by Catherine Lawson, we obtained an experimental 3D map volume (shown below) of a class I CAP-dependent transcription activation complex using single particle averaging of 2D electron microscopy images. The EM map volume and fitted coordinates are deposited in the EM Databank (EMD-5127) and PDB (id 3iyd).

Electron microscopy reconstruction (20 Å resolution) of a transcription initiation complex from Escherichia coli comprising RNA polymerase holoenzyme (purple with alpha subunit C-terminal domain shown in green), catabolite activator protein (blue), and DNA (tan). The background is an electron micrograph of reconstituted complex particles in negative stain (Hudson et al., 2009).
