A cation-π interaction between Trp128 and Arg 129 in alpha thrombin (PDB: 2BDY). The guanidinium carbon is 3.6 angstroms from the top edge of the Trp. It is expected that the epsilon nitrogen forms the primary cation-π interaction. The electrostatic and Van der Waals interaction energies were calculated to be -3.29 kcal/mol and -3.08 kcal/mol respectively by the CaPTURE program (https://capture.caltech.edu/result.cgi).
