WebOxygen Bound to Myoglobin A later structure of myoglobin, PDB entry 1mbo, shows that oxygen binds to the iron atom deep inside the protein. So how does it get in and out? The answer is that the structure in the PDB … Like hemoglobin, myoglobin is a cytoplasmic protein that binds oxygen on a heme group. It harbors only one globulin group, whereas hemoglobin has four. Although its heme group is identical to those in Hb, Mb has a higher affinity for oxygen than does hemoglobin. This difference is related to its different role: whereas hemoglobin transports oxygen, myoglobin's function is to store oxygen.
