Structure and Synthesis of Hemoglobin

This figure shows the heme group and the portion of the hemoglobin protein that is directly attached to the heme. When hemoglobin is deoxygenated (left), the heme group adopts a domed configuration. When hemoglobin is oxygenated (right), the heme group adopts a planar configuration. As shown in the figure, the conformational change in the heme group upon oxygenation causes the entire hemoglobin protein to change its conformation as well.

Biosynthesis of Hemoglobin | Hemoglobin | Biochemistry

Metal ions are ideal for use in biological systems due to their ability to coordinate with (bind) and then release ligands. The most common metal used in the body is iron, which plays a central role in almost all living cells. For example, iron complexes are used in the transport of oxygen in the blood and tissues.

This is a molecular model of hemoglobin with the subunits displayed in the ribbon representation. A ribbon representation traces the backbone atoms of a protein and is often used to represent its three-dimensional structure. The four heme groups are displayed in the ball-and-stick representation.

To understand the oxygen-binding properties of hemoglobin, wewill focus briefly on the structure of the protein and the metalcomplexes embedded in it.

Biochemistry notes BI ch3 - Biology Junction

Hemoglobin consists of four protein chains, each about thesize of a myoglobin molecule, which fold to give a structure thatlooks very similar to myoglobin. Thus, hemoglobin has fourseparate heme groups that can bind a molecule of O2.Even though the distance between the iron atoms of adjacent hemesin hemoglobin is very large between 250 and 370nm the act of binding an O2molecule at one of the four hemes in hemoglobin leads to asignificant increase in the affinity for O2 binding atthe other hemes.
