Heme and globin
Web17 mei 2024 · Hemoglobin is a large molecule made up of proteins and iron. It consists of four folded chains of a protein called globin, designated alpha chain 1 and 2, and beta chain 1 and 2. Each of these globin molecules is bound to a red pigment molecule called heme, which contains an ion of iron (Fe 2+) (Figure 16.3. 3 ). The globins are a superfamily of heme-containing globular proteins, involved in binding and/or transporting oxygen. These proteins all incorporate the globin fold, a series of eight alpha helical segments. Two prominent members include myoglobin and hemoglobin. Both of these proteins reversibly bind oxygen via a heme prosthetic group. They are widely distributed in many organisms.
