ATOMIC RESOLUTION CRYSTAL STRUCTURE AQUOMET-MYOGLOBIN FROM SPERM WHALE AT ROOM TEMPERATURE
Overview
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.
About this Structure
