Abstract

Ligand binding and unbinding are important aspects of the function of myoglobin and hemoglobin. The details of the mechanism by which these occur are, however, not yet clear. Molecular dynamics simulations^1,2 have addressed the issue of escape trajectories for CO from their original binding site in the protein, but these require additional experimental input to better isolate the key steps of the unbinding process.
