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 (Haemoglobin in many varieties of English) is a tetramer consisting of two dimers that binds to oxygen. Hemoglobin is the oxygen binding protein of red blood cells and is a globular protein with quaternary structure.Hemoglobin consists of four polypeptide subunits; 2 alpha chains and two beta chains. Hemoglobin transports oxygen in the blood from the lungs to the rest of the body.The three-dimensional structure of hemoglobin was solved using X-ray crystallography in 1959 by Max Perutz.emoglobin consists of four polypeptide subunits; 2 alpha chains and two beta chains.
