About BION-2
Ions are essential component of the cell and frequently are found bound to various macromolecules, in particular to proteins. A binding of an ion to a protein greatly affects proteins biophysical characteristics and needs to be taken into account in any modeling approach. However, ion’s bounded positions cannot be easily revealed experimentally, especially if they are loosely bound to macromolecular surface. The BION-2 web server predicts non-specifically surface-bound ions.
