Basic Search

From any page on the site, a Basic Search can be run by entering a search term in the top Search Bar.

As you enter a term, you will see suggestions appearing in the dropdown menu that appears below the search bar. The suggestions are grouped by attribute name, indicating in the specific field or fields in which the search term was found.

You can click on an item in the dropdown menu to see results matching only that particular attribute, or click the
Search icon to see results matching multiple fields.


Advanced Search

The Advanced Search Query Builder tool allows you to construct complex boolean queries by specifying values for a wide range of structure attributes.

Text-based queries can be combined with sequence and structure similarity searches.

Search results can be returned at the structure, entity, or assembly level, and viewed in a variety of formats, for example, as a summary view, an images only gallery view, or in a Tabular Report format.

Any query and its results can be further refined by selecting additional criteria from the 'Refinements' panel.

Search by Sequences

Search protein and nucleic acid sequences using the mmseqs2 method to find similar protein or nucleic acid chains in the PDB.

The new Advanced Search Query Builder tool can be used to run sequence searches, and to combine the results with the other search criteria that are available.

Search by Unreleased & Access New Entries

The PDB archive is updated weekly in two phases

Phase I: Every Saturday by 3:00 UTC, for every new entry, wwPDB website provides sequence(s) (amino acid or nucleotide) for each distinct polymer and, where appropriate, the InChI string(s) for each distinct ligand and the crystallization pH value(s).

Phase II: Every Wednesday by 00:00 UTC, all new and modified data entries will be updated at each of the wwPDB FTP sites.

As of Tue Dec 01 2020 there are 171916 structures.

Explore the PDB Archive

The Explore the PDB Archive feature on the home page allows you to quickly view the archive in a series of pie charts. Each chart displays a statistical drilldown of the data in the following categories:

  • Organism
  • Taxonomy
  • Experimental Method
  • Resolution (Å)
  • Release Year
  • Entity Polymer Type
  • Enzyme Classification
  • Membrane Protein

In addition, the drilldown data includes links to the Search Results page, where the data can be explored in greater detail.
