Simple text searches at are now easier and more accurate. Text searching from the top query bar uses the combined power of the open source Apache Solr platform and an indexing of PDBx/mmCIF data.

Access this new functionality by entering a search term or terms in the top bar of any RCSB PDB page and hitting ‘Go’ or a keyboard return. Searches for multiple words (for example, insulin receptor) and queries for adjacent words enclosed in double quotation marks (for example, “insulin receptor”) may return different results. The first search finds results where the words appear anywhere in the entry, whereas the second returns results where the search terms appear exactly as ordered.

Search results are assigned “Match Scores” to help indicate the relevance of the result and to sort structures from “Higher to Lower” matches and vice versa. The figure below shows a search for the name Perutz.

Search terms that appear in certain PDBx/mmCIF tokens are highlighted (e.g., structure or citation author, citation, entity name or description, keywords, structure title).

RCSB PDB is looking for Scientific Software Developers and Postdoctoral Fellows in to join the Development Team at UC San Diego.

We are looking for talented and highly motivated Scientific Software Developers and Postdoctoral Fellows to join our multidisciplinary development team.

The Challenge: Develop innovative analysis, integration, query, and visualization tools for 3D biomolecular structures to help accelerate research and training in biology, medicine, and related disciplines. In these projects, we employ the latest advances in computer science to develop highly interactive features and scalable services and workflows. This is a unique opportunity to engage in leading edge research, development, and outreach activities of the RCSB PDB with worldwide impact. For more, visit our Careers page or Contact Us with questions.

A snapshot of the PDB archive ( as of January 1, 2018 has been added to and Snapshots have been archived annually since January 2005 to provide readily identifiable data sets for research on the PDB archive.

The directory 20180101 includes the 136,472 experimentally-determined coordinate files and related experimental data available at that time. Atomic Coordinate and related metadata are available in PDBx/mmCIF, PDB, and XML file formats. The date and time stamp of each file indicates the last time the file was modified. The snapshot is 1034 GB.
