Protein oxidation in plant mitochondria

Camilla Brygger & Maria Nybo Petersen

Studenteropgave: Semesterprojekt

Abstrakt

The purpose of this project was to map and understand the chemistry behind Reactive Oxygen Species and some of the mechanism that produce and prevents reactive oxygen species, to study the problem about how the mitochondria respiratory pathway is affected by oxidative stress in plant cells. Articles have reviewed that the most affected pathway is without doubt the Krebs cycle we have found indications of at least five proteins affected by reactive oxygen species. Furthermore it is found that the production of pyruvate, needed to start the Krebs cycle, is affected in several ways. It is also found that other proteins such as molecular chaperones and proteins involved with the antioxidant system have been affected. It is found that the area of ROS in plant mitochondria is a new field of research and therefore limited. Because of this there has only been made a few experiments and conclusions. While working with this project more questions have arised than questions answered. We hope that the future will bring more knowledge about ROS production and proteins in the mitochondria, and thereby making the knowledge more complete and hopefully even more useful to scientist and students all over the world.
