This protein has four porphyrin rings, each of which contains a Fe2+ ("f-e-2 plus") ion.
This protein has an abnormally high pKa value when an ion pair is generated between a histidine and an aspartic acid residue, which occurs when the proton concentration around this protein is high. The central structure of this protein is stabilized by a histidine residue in its F alpha helix chain, and BPG interacts with this protein to stabilize its T state. This protein functions as an alpha two, beta two tetramer in adult humans, and heterozygotes for a condition afflicting this proteins have an advantage in malaria ridden areas. This protein has four porphyrin rings, each of which contains a Fe2+ ("f-e-2 plus") ion. For 10 points, name this protein which can carry both carbon monoxide and oxygen.
