What are Structure Summary pages and related tabs?

Each 3D structure accessible from RCSB.org, including experimental or Protein Data Bank (PDB) structures and Computed Structure Models (CSMs), has a variety of associated data.

• Primary data include information from the specific 3D structure, e.g., structural coordinates, sequences of biological macromolecules, information about any small molecules/ligands present in the structure, details about structure determination method(s), authors and publication information.
• Other data include
• Information related to one or more components integrated from other data resources, mapped onto the 3D structure(s), e.g., functional and mutational information about macromolecule(s) from UniProt
• Organization and classification of one or more components included in the PDB entry as identified from external resources, e.g., sequence and structural domains from Pfam, SCOP, CATH, and ECOD; molecular functions, cellular location, biological functions from Gene Product Annotations; and membrane annotations.

For each experimental structure, data are presented in a manner that can be easily accessed, visualized, downloaded, and analyzed. This presentation also allows you to use pieces of information to visualize it, integrate information from other bioinformatics resources, and/or query the entire archive for other examples like it.

For each CSM, primary and a limited amount of other data are presented for easy access, visualization and analysis.

This section describes how different types of information about an entry are presented on the Structure Summary and related pages. It also describes how you can use this information to learn more about the properties, interactions, and functions of the specific molecule(s) being studied.

How to access the Structure Summary and related tabs?

• If you know the specific identifier for the 3D structure you wish to explore (e.g., PDB ID for experimental structures and AlphaFold or Model Archive IDs for CSMs), type the identifier into the top search bar on RCSB.org pages.
• If you do not have a specific 3D structure of interest, you can Search or Browse the archive based on various parameters to identify one or more structures to explore. Click on the ID listed in the search results to explore Structure Summary, Structure, Annotations, Experiment, Sequence, Genome, Ligands, and Versions.
