Time-resolved crystallography of myoglobin ligand dissociation

Why?
This was the highlight of my undergraduate course in protein structure and dynamics. The animation is a time-resolved combination of x-ray crystal structures of myoglobin's haem binding site. From the electron density maps you can see not only the amino acid residues of the active site, but also the movement of the dissociating ligand and the residues of the active site. The visualisation of protein fluctuation on such a scale is truly beautiful!—Charles Evans
