Forschern am Göttinger Max-Planck-Institut für biophysikalische Chemie ist es gelungen, dem Ribosom - der Proteinfabrik der Zelle - beim Bau der Proteine zuzusehen. Sie "filmten", wie Aminosäure-Transporter während der Proteinproduktion durch das Ribosom geschleust werden. Die dabei eingesetzte Technik der zeitaufgelösten 3D-Kryo-Elektronenmikroskopie erlaubt faszinierende neue Einblicke in die Funktionsweise der Proteinfabrik. (Nature, 15. Juli 2010)
Ribosomen - die Proteinfabriken der Zelle - sind molekulare Hochleistungsmaschinen. Nach genetisch kodierten Produktionsplänen fertigen sie Proteine - die universellen Werkzeuge aller Zellen. Proteine bauen Muskeln auf, transportieren zelluläre Fracht, empfangen und übermitteln Signale, bringen chemische Reaktionen in Gang oder sorgen für Wachstum und Bewegung.
