pyPDBeREST

A python wrapper for the PDBe REST API, inspired by pyEnsemblRest.

Setup

Easy install from github using pip.

$ pip install --upgrade http://github.com/biomadeira/pyPDBeREST/zipball/master

If you want to mess up with the source code.

git clone https://github.com/biomadeira/pyPDBeREST.git
cd pyPDBeREST
sudo python setup.py install

Example usage

For a full set of examples and more details on all functionality see these notes. For the impatient see below.

Quickstart

# loading the module...
from pdbe import pyPDBeREST
p = pyPDBeREST()

Alternatively overriding the base url for the endpoints…

# using the dev branch of the api
p = pyPDBeREST(base_url='http://wwwdev.ebi.ac.uk/pdbe/')

Printing out all the available method endpoints…

print(p.endpoints())

The following endpoints are available:
    EMDB
    SSM
    SEARCH
    SIFTS
    COMPOUNDS
    TOPOLOGY
    VALIDATION
    PDB
    PISA

Printing out all the available endpoints for one of the top level methods…

print(p.PDB.endpoints())

The following endpoints are available:
    getReleaseStatus
    getBindingSites
    getObservedRanges
    getRelatedPublications
    getResidueListingChain
    getNmrResources
    getExperiments
    getSecondaryStructure
    getVariousUrls
    getModifiedResidues
    getSummary
    getResidueListing
    getPublications
    getLigands
    getMutatedResidues
    getMolecules

GET

# example of a GET query...
data = p.PDB.getSummary(pdbid='1cbs')
print(data)

POST

Not all endpoints enable post requests. Those will raise a NotImplementedError() exception.

# an example POST query...
# up to 1000 pdb ids can be queried with post methods
data = p.PDB.getSummary(pdbid='1cbs, 2pah', method='POST')
print(data)
