PDB Archive Downloads

Please note that the FTP file download protocol in the PDB archive has been deprecated since November 1st 2024 (announcement).

The PDB archive and versioned archive are updated every Wednesday at 00:00 UTC.

wwPDB: https://files.wwpdb.org, rsync://rsync.wwpdb.org
RCSB PDB (US): https://files.rcsb.org, rsync://rsync.rcsb.org (see the download protocol below)
PDBe (UK): ftp.ebi.ac.uk/pub/databases/pdb/
PDBj (Japan): ftp://ftp.pdbj.org, https://files.pdbj.org, rsync://rsync.pdbj.org

The PDB versioned sites (See announcement) are updated the same time when the main archive sites are updated.

wwPDB: https://files-versioned.wwpdb.org, rsync://rsync-versioned.wwpdb.org
RCSB PDB (US): https://files-versioned.rcsb.org, rsync://rsync-versioned.rcsb.org
PDBe (UK): ftp://ftp.ebi.ac.uk/pub/databases/pdb_versioned/
PDBj (Japan): ftp://ftp-versioned.pdbj.org/, https://files-versioned.pdbj.org, rsync://rsync-versioned.pdbj.org

New Sequence and InChI

Every Saturday by 3:00 UTC, for every new entry the wwPDB website provides:

Sequence(s) (amino acid or nucleotide) for each distinct polymer (new_release_structure_sequence.tsv)
InChI string(s) for each distinct ligand (new_release_structure_nonpolymer.tsv), where appropriate
Crystallization pH value(s) (new_release_crystallization_pH.tsv)

Download Protocols

Every Wednesday from 00:00 UTC, all new and modified data entries will be updated at each of the wwPDB repository sites. The PDB archive is quite large, requiring over 1TB of storage, and continues to grow with each weekly update.

All files mentioned above are available via 3 different protocols: ftp, https and rsync. For individual file downloads we recommend https. The ftp protocol will be gradually phased out. For bulk file downloads we recommend rsync, see more instructions about rsync below.

Archive Snapshots

The annual archive snapshots provide the data in the archive at the start of each year or at selected milestone moments. These data may be used to provide a stable set of entries for analysis and allow users to see changes introduced due to remediation efforts by wwPDB.

Access to these snapshots is available through HTTP, rsync, FTP, and AWS sync protocols.

HTTP Protocol

RCSB PDB (US/AWS): https://s3snapshots.rcsb.org

PDBj (Japan): https://snapshots.pdbj.org

RSYNC Protocol

PDBj (Japan): rsync -avy snapshots.pdbj.org:: .

FTP Protocol

PDBj (Japan): ftp://snapshots.pdbj.org

AWS SYNC Protocol

RCSB PDB (US/AWS): s3://pdbsnapshots/

AWS SYNC Instruction:

Install AWS CLI tool
- List all PDB Snapshot objects
- aws s3 ls s3://pdbsnapshots/ --no-sign-request
- When you see a result like:
- 20250101/ PRE 20250101/
- - PRE: This indicates that the listed item is a "prefix" or "folder" in the S3 bucket, not a file object. This is how S3 organizes files logically into folders.
  - 20250101/: This is the prefix (or "folder") in the S3 bucket. It's not an actual folder in the traditional sense, but rather a common prefix used to group objects.
- Sync PDB Snapshots
- All PDB Snapshot objects
- aws s3 sync s3://pdbsnapshots/ ./local-directory/ --no-sign-request
- Specific PDB snapshot object (e.g., /20250101)
- aws s3 sync s3://pdbsnapshots/20250101/ ./local-directory/20250101 --no-sign-request
