PDB2PQR is a python software package that automates many of the common tasks of preparing structures for continuum solvation calculations, providing a platform-independent utility for converting protein files in PDB format to PQR format.

Some of the other functionalities of PDB2PQR include:

• adding a limited number of missing heavy (non-hydrogen) atoms to biomolecular structures,
• estimating titration states and protonating biomolecules in a manner consistent with favorable hydrogen bonding,
• assigning charge and radius parameters from a variety of force fields.
