pdb2pqr - 2.1.1+dfsg-5 main

PDB2PQR is a Python software package that automates many of the common
tasks of preparing structures for continuum electrostatics calculations.
It thus provides a platform-independent utility for converting protein files
in PDB format to PQR format. These tasks include:
* 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
* Assigning charge and radius parameters from a variety of force fields
.
This package also includes PropKa, a tool to modify the protonation state of
protein structures in the Protein Data Bank (PDB) format to match a given pKa
value. It can also be used to refine NMR structures, which often yield
inaccurate pKa values for some residues.
