For 10 points, name this iron-containing protein that carries oxygen in the blood.
BPG allosterically induces this protein to unbind from its primary ligand, which is incorporated into one of four octahedral complexes, and which has a sigmoidal binding curve due to cooperative binding, as observed by the elder Bohr. The unusual pigmentation of jaundice patients is due to bilirubin, produced when this protein is catabolized. A pathological glutamic acid-to-valine point mutation in the sixth residue of this protein's porphyrin-containing beta-globin will cause it to form fibers; when that happens, the cells that transport it are deformed into a sickle shape, resulting in a form of anemia.
