The ability to predict the mechanisms and the associated rate constants of protein–ligand unbinding is of great practical importance in drug design. In this work we demonstrate how a recently introduced metadynamics-based approach allows exploration of the unbinding pathways, estimation of the rates, and determination of the rate-limiting steps in the paradigmatic case of the trypsin–benzamidine system. Protein, ligand, and solvent are described with full atomic resolution. Using metadynamics, multiple unbinding trajectories that start with the ligand in the crystallographic binding pose and end with the ligand in the fully solvated state are generated. The unbinding rate koff is computed from the mean residence time of the ligand. Using our previously computed binding affinity we also obtain the binding rate kon. Both rates are in agreement with reported experimental values. We uncover the complex pathways of unbinding trajectories and describe the critical rate-limiting steps with unprecedented detail. Our findings illuminate the role played by the coupling between subtle protein backbone fluctuations and the solvation by water molecules that enter the binding pocket and assist in the breaking of the shielded hydrogen bonds. We expect our approach to be useful in calculating rates for general protein–ligand systems and a valid support for drug design.

The vibroluminescence of carbon monoxide excited by activated nitrogen is investigated under high resolution in the fundamental and harmonic regions. The rotational population, corrected in some cases for self-absorption, shows a Boltzmann distribution characterized by a rotational temperature of 400 °K, but the vibrational population definitely shows a non-Boltzmann distribution which coincides very accurately with a Treanor-type distribution. This distribution is due, as explained by the theory of Treanor, to the anharmonicity of the molecules and to the inefficiency of the vibration–translation transfer. The variation of the number of vibrational quanta as a function of time allows a determination of the vibration–vibration rate transfer and shows the intervention of a deactivation process interpreted as due to CN radicals. Results in the harmonic region give ratios of the square of matrix elements which are compared with theoretical values and with other experimental values.
