Prediction of binding sites for different types of ions in protein 3D structure context is a complex challenge for biophysical computational methods. One possible approach involves using empirical, also called as knowledge-based, potentials. In the current study, we present a new GPGPU program complex, PIONCA (Protein-ION CAlculator) for efficient generation of empirical potentials for protein-ion interaction, provide description of its characteristics, and also present a publically available online service based on it.
