Scientists led by Prof. Thomas Becker, Director of the Institute of Biochemistry and Molecular Biology at the University Hospital Bonn (UKB), has found new insights into the structure of ATP synthase, the turbine of the cells’ power plants, the mitochondria.

What Is The Role Of Atp Synthase In Photosynthesis

A so-called “molecular chaperone”, the protein Hsp70, does more work in the aging of proteins than previously thought. As the researchers found, Hsp70 not only works as a “folding assistant” of proteins in mitochondria, but also promotes the assembly of ATP synthase. The new research provides important research for understanding how ATP synthase is built and is now published in the well-known journal Nature Communications.

Does Atp Synthesis Require Oxygen?

As you know, there are many cells in the human body. If one thinks of each cell in the human body as a city with different buildings, then the mitochondrion is the electron. Mitochondria produce ATP (adenosine triphosphate), which is necessary for various activities in the cell. In particular, nerves and muscles need a lot of energy for their work. As usual in power plants, internal workers are needed, and in the case of mitochondria, these are the proteins that are imported into the power plant from the cytosol.

The Hsp70 protein is involved in the import of many of these proteins into the mitochondria, the mitochondrial matrix, where the folding of the proteins is arranged so that they take the correct shape and do not clump together. Many proteins form together with their partners in a functional group called a protein complex. ATP synthase is one of those complex proteins, located in the inner membrane. The ATP synthase provides the majority of cellular energy and can be considered the turbine of electrical machinery.

“The ATP synthase protein complex consists of a rotating rotor that is driven by the back transport of protons in the mitochondrial matrix. This part is connected to the head of the enzyme through the attachment, the stator molecule. . The rotation of the rotor is given to the catalytic head, resulting in the production of ATP. The way to build and connect together the stator and the installation head was only partially understood before, “the story which Prof. Thomas Becker.

The research group led by Prof. Thomas Becker at UKB is now able to find new information on this association. Scientists have identified a central function of the protein Hsp70 in the creation of ATP synthase: Hsp70 is not only a folding aid, but also helps to assemble this protein complex, according to the researchers.

Dr. Jiyao Song, a post-doctoral researcher in the group of Prof. Becker, found that Hsp70 is involved with partner proteins in the assembly of the catalytic head. With the team of Dr. Dominic Winter, he was able to show that the subunits of ATP synthase accumulate in Hsp70 when the assembly of ATP synthase is inhibited. Dr. knew more. Song of Hsp70 monitors the connection of the catalytic head to the stator.

Thus, the mitochondrial Hsp70 fulfills a dual function in the formation of ATP synthase: the assembly of the catalytic head and the controlled connection of the head to the stator.

This research project within the Collaborative Research Center 1218 provides new insights into the binding of Hsp70 and the formation of a central protein machinery for energy production in cells. “Defects in the formation of ATP synthase or mitochondrial Hsp70 lead to diseases, especially of the body. Therefore, new results can make important contributions to the understanding of these disorders, “said Prof. Dr. Thomas Becker.

In biology, chemiosmosis refers to the process of moving ions (eg protons) across a biological membrane, and as a result, a

This means that ions will move from an area of ​​higher concentration to an area of ​​lower concentration.

This process is similar to osmosis where water molecules move around. In the case of chemiosmosis, however, it involves ions moving across the membrane; in osmosis, water molecules. However, both processes require a

. The difference in pressure between the two sides of the membrane drives osmosis. As for chemiosmosis, the movement of ions is driven by a

Not only is chemiosmosis similar to osmosis. It’s the same with other forms of slow transportation,  like facilitating transportation. A similar principle is used. Ions move

. In addition, the molecule is transferred to the other side of the membrane with the help of membrane proteins. Membrane proteins help ions to move around since the membrane does not allow ions to pass through easily, due to its

These proteins in the membrane facilitate their activity by acting as a temporary vessel or as a channel or channel. Chemiosmosis uses membrane proteins to transport specific ions. Also, it does not require chemical energy (e.g. ATP) as opposed to an energy transport system to do so. In chemiosmosis, the formation of an ion gradient leads to the formation of

Mitochondrial Atp Synthase: Architecture, Function And Pathology

In eukaryotes, it occurs in mitochondria during cellular respiration and in chloroplasts during photosynthesis. Prokaryotes do not have organelles and therefore chemiosmosis occurs within their cells.

Etymology: “chemi-“, related to medicine, and “osmosis”, from the Ancient Greek “ὠσμός” (“ōsmós”), meaning “to supply”. Test: chemosmosis. See also osmosis,

According to the chemiosmotic theory, chemiosmosis is driven by an electric current that is required during the production of ATP. This theory was established by Peter D. Mitchell (1920 – 1992), a British biochemist. (Ref. 1)

Mitchell’s theory, however, was not immediately accepted until a significant foundation was laid on the proton pump. The discovery of ATP synthase and the difference in pH on the thylakoid gave the bioenergetics community the benefit of its concept. (Ref. 2)
