Researchers at the BSC and the IRB Barcelona unveil crucial information about the protein transporter of oxygen, which opens up the possibility to optimize its function by introducing modifications. The transport of oxygen in blood is undertaken by hemoglobin, the largest component of red blood cells. This protein collects oxygen in respiratory organs, mainly in the lungs, and releases it in tissues in order to generate the energy necessary for cell survival.
Hemoglobin, the protein in red blood cells responsible for ferrying oxygen from the lungs to the body's tissues (and for carrying carbon dioxide in the opposite direction), is composed of four separate amino acid polypeptide chains, or globins.ach polypeptide in hemoglobin folds to create a pocket for a heme unit, which actually carries the oxygen and carbon dioxide. Finally, the four globin chains come together due to further non-covalent interactions to produce the quaternary structure of the complete hemoglobin protein.
