Structure of relaxed-state human hemoglobin: insight into ligand uptake, transport and release

J. D. Jenkins, F. N. Musayev, R. Danso-Danquah, D. J. Abraham and M. K. Safo

Synopsis: The crystal structure of a human carbonmonoxy hemoglobin has been determined at 2.8 Å resolution. The structure, which is in a relaxed conformation, shows rotation of [beta]His63(E7) out of the distal pocket, creating a ligand channel to the solvent.
