• queryUniprot() - query UniProt and parse the results as a dictionary
• UniprotRecord - a wrapper from UniProt data with functions including parsing PDBs
• searchUniprot() - search UniProt and return a UniprotRecord

CATH

The following class and its functions can be used to search and retrieve CATH data:

• CATHDB - parse, handle and navigate the tree-like structure of the CATH database

DALI

The following class and functions can be used to search and retrieve data using the DALI structure alignment server:

• searchDali() - search for similar structures using DALI
• DaliRecord - fetch and handle outputs from DALI searches
• daliFilterMultimers() - filter DALI results to obtain multimers of a particular size

QuartataWeb

The following classes and functions can be used to search and retrieve data using the QuartataWeb structure alignment server:

• QuartataWebBrowser - class based on the Splinter web browser package to search QuartataWeb
• QuartataChemicalRecord - class to handle the outputs of QuartataWeb searches
