A Python 3 toolkit for performing searches with the RCSB Protein Data Bank (PDB). This can be used to perform advanced searches for PDB IDs matching various criteria, as well as to look up information associated with specific PDB IDs. This tool allows standard operations that can be perfomed from within the PDB website (BLAST, PFAM lookup, etc.) to be performed from within Python scripts.
Examples of each function and its associated output can be found in
If you use this module for any published work, please consider citing the accompanying paper
Gilpin, W. "PyPDB: A Python API for the Protein Data Bank." Bioinformatics, Oxford Journals, 2015.
As of November 2020, pypdb is undergoing significantly refactoring in order to accomodate changes to the RCSB PDB API and extend functionality. We regret any breaking changes that occur along the way. The previous version of pypdb is available here; however, it will no longer function to to the RCSB API being changed.
We very much welcome contributors and pull requests
Install using pip:
$ pip install pypdb
To install the development version, which contains the latest features and fixes, install directly from GitHub using
$ pip install git+git://github.com/williamgilpin/pypdb
If you need to install directly from setup.py,
$ python setup.py install
Test the installation, and check that the code successfully connects to the PDB, navigate to the root directory and run
This code has been designed and tested for Python 3.
This package can be used to get lists of PDB IDs associated with specific search terms, experiment types, structures, and other common criteria.
Given a list of PDBs, this package can be used to fetch any data associated with those PDBs, including their dates of deposition, lists of authors and associated publications, their sequences or structures, their top BLAST matches, and other query-specific attributes like lists of a ligands or chemical structure.
A set of demos is included in the iPython notebook demos.ipynb. A static version of this notebook (for viewing) is available as demos.html
Issues and Feature Requests
If you run into an issue, or if you find a workaround for an existing issue, we would very much appreciate it if you could post your question or code as a GitHub issue.
