Protein Team Produces Molecular Barrels

Researchers show that two protein machineries collaborate on the development of barrel structures in the mitochondria

(PresseBox) (Freiburg, )
Research groups headed by Prof. Dr. Nikolaus Pfanner, Dr. Nils Wiedemann, and Dr. Thomas Becker from the University of Freiburg and their colleagues have demonstrated how molecular protein barrels form in the outer membrane of the mitochondria, the powerhouses of the cell. Their studies revealed that two protein machineries cooperate in an unexpected way. The researchers published their findings in the scientific journal "Cell".

Mitochondria are essential for the survival of the cell, rendering such vital services as providing the energy for cell metabolism. Mitochondria are surrounded by two membranes. The outer membrane contains characteristic proteins with a barrel-like structure,
