PDB structure files, chemical component files, and several other
files are available for download via http. These URLs are useful in
scripted downloads using utilities such as
Note: The behavior of web browsers upon using these URLs may
vary. Depending on the browser configuration, some URLs may display a
file in the browser (either as plain text or in a graphical viewer),
and some URLs may trigger a file download to the user's computer.
PDB structure files are available in several file formats (PDB, CIF,
XML), compressed or uncompressed, and with an option to download a
file containing only header information (no coordinates).
Note: In addition to the download links in the table below,
further links for retrieving information on any PDB structure
(experimental, theoretical, unreleased, or obsolete) are available
on the FAQ page.
Several files are available for each chemical component. Chemical
components are identified by a 3 character identifier, such as 'HEM' in
the following examples.
A FASTA formatted file ("ss.txt") generated using DSSP
with sequences and secondary structures is available at:
The "Structure integration with function, taxonomy and sequence
initiative" aims to work towards the integration of various
bioinformatics resources. SIFTS files are available for download from
the RCSB PDB website using the following syntax.
The RCSB PDB (citation) is managed by two members of the Research Collaboratory for Structural Bioinformatics:
RCSB PDB is a member of the
