摘要
By using multiple molecular dynamics trajectories of photolyzed carbon monoxide (CO) within crystallized myoglobin, a quantitative description of CO diffusion and corresponding kinetics was obtained. Molecular dynamics results allowed us to construct a detailed kinetic model of the migration process, shedding light on the kinetic mechanism and relevant steps of CO migration and remarkably-well reproducing the available experimental data as provided by time-resolved Laue x-ray diffraction.
