Easy to Install¶
As seen in the installation page, PypKa is easilly installed from the command line.
Easy to Use¶
API & CLI¶
Every interface has its pros and cons. With PypKa you can choose to run you calculations via a python API or from the command-line. In the future we will present a webserver interface as well.
Fast and accurate¶
As a Poisson-Boltzmann-based pKa predictor, PypKa provides an
interesting trade-off between speed and accuracy. You can also
manually set some input parameters such as
sites, to adjust the balance between
accuracy and speed as you please. Further speed gains can be achieved
by taking advantage of the highly scalable multiprocessing
Flexibility of Input Structures¶
PypKa supports both the Protein Data Bank and GROMACS input format and
the most popular atomistic force-fields (AMBER, CHARMM & GROMOS) as
well as experimentally determined structures. These structures are
preprocessed using a modified version of PDB2PQR according to the
Lipidic Systems Support¶
It is possible to run calculations on membrane proteins, and in the future, on lipids. Currently only some lipids are supported (DMPC, POPC, POPE and cholesterol) but more will be added. To use this feature the user is required to name the lipids in their structures according to the PypKa definition.
