binana
BINANA (BINding ANAlyzer) is a python-implemented algorithm for analyz
...The program identifies key binding characteristics like hydrogen bonds, salt bridges, and pi interactions. As input, BINANA accepts receptor and ligand files in the PDBQT format. PDBQT files can be generated from the more common PDB file format using the free converter provided with AutoDockTools. As output, BINANA describes ligand binding.
