When oxygen binds to the iron complex, it causes the iron atom to move back toward the center of the plane of the porphyrin ring (see moving diagram). At the same time, the imidazole side-chain of the histidine residue interacting at the other pole of the iron is pulled toward the porphyrin ring. This interaction forces the plane of the ring sideways toward the outside of the tetramer, and also induces a strain in the protein helix containing the histidine as it moves nearer to the iron atom. … WebHemoglobin, the protein molecule found in red blood cells, is responsible for carrying oxygen to the body's tissues. Each molecule of hemoglobin is made up of 4 subunits, each carrying a molecule of heme.
