PDBj

PDBj (Protein Data Bank Japan) is one of the member organizations of the worldwIDE Protein Data Bank and serves as a public archive for experimentally determined structures of proteins, nucleic acids, and other macromolecules. It is operated under the Institute for Protein research at Osaka university and ACTs as the Japanese hub for structure data that is shared globally with partner Databases.

What it does

The service collects, validates, and distributes three-dimensional structural data derived from techniques such as X-ray crystallography, NMR spectrOSCopy, and electron microscopy. Researchers deposit their experimental results, and the archive makes those records freely searchable and downloadable for the scientific community.

Key capabilities

• Structure search and browsing: locate entries by identifier, sequence, keyword, or advanced query filters.
• Data download: retrieve coordinate files and related experimental metadata for analysis pipelines.
• Deposition services: subMIT new structures for validation and public release.
• Derived resources: access associated tools and databases such as sequence and classification resources mAIntained by the Same group.
• documentation and tutorials: guidance for using the archive and its file fORMats.

Who it is for

The archive primarily serves structural biologists, biochemists, computational biologists, and Bioinformatics developers who need reliable reference structures. machine learning practitioners working on protein folding, structure prediction, or molecular modeling often use such public archives as a source of training and evaluation data. educators and students in the life sciences may also find it useful for teaching and reference.

How to get started

1. Open the official PDBj website in a web browser.
2. Use the search box or browse links to find structures or resources of interest.
3. Review an entry page to inspect Metadata, experimental details, and available files.
4. Download coordinate files or related data for your own analysis.
5. If you have new experimental structures, follow the deposition Workflow and check validation feedback before release.

Pricing and access

PDBj is a public scientific resource and access to its data is Generally Free. No subscription is typically required for browsing or downloading entries. Specific deposition workflows, supported formats, and any usage terms may change over time, so consult the official documentation before relying on the service for production or publication work. Because it is a data archive rather than a commercial AI product, no software license fees or credit-based pricing should be assumed.
