PDB2PQR

PDB2PQR is a remarkable open-source and free Python software package designed to automate a multitude of common tasks required to prepare structures for continuum electrostatics calculations. It provides a platform-independent utility that converts protein files from PDB format to PQR format with remarkable effectiveness. The software takes these tasks in stride, including adding a limited number of missing heavy atoms to biomolecular structures, determining side-chain pKas, placing missing hydrogens, optimizing the protein for favorable hydrogen bonding, and assigning charge and radius parameters from a variety of force fields.

One of the most impressive features of PDB2PQR is its ability to perform all these tasks with remarkable fluidity, optimizing essential structures in such a way that one can enjoy the full power of electromagnetic fields without incurring any difficulties associated with missing or ill-defined structures. The software's ability to add heavy atoms and detect side-chain pKas is a significant milestone, providing an unparalleled level of accuracy during molecular dynamic simulations.

Additionally, its charge assignment methodology ensures that the user has complete control over the computation of electrostatic fields. The software is versatile in its functionality, offering multiple options for force-field parameters required for different simulations. This software is a valuable tool for researchers that require accuracy, automation, and an efficient platform-independent utility for converting protein files from PDB to PQR formats.
