Webserver & command-line tool for search of Apo (unbound) protein structures from Holo (bound) forms and vice versa.

• customizable search of Apo-Holo pairs in the PDB
• alignment to the query structure
• batch mode for fast parallel dataset processing
• visualization via Molstar and PyMol
• public documented REST-API

Web interface is now available at: https://apoholo.cz

Standalone Python command line application: https://github.com/ioChris/AHoJ
