ATOMIC RESOLUTION CRYSTAL STRUCTURE AQUOMET-MYOGLOBIN FROM SPERM WHALE AT ROOM TEMPERATURE
OverviewOverview
The crystal structures of myoglobin in the deoxy- and carbon monoxide-ligated states at a resolution of 1.15 angstroms show that carbon monoxide binding at ambient temperatures requires concerted motions of the heme, the iron, and helices E and F for relief of steric inhibition. These steps constitute the main mechanism by which heme proteins lower the affinity of the heme group for the toxic ligand carbon monoxide.
