Neue Erkenntnisse zum Proteinimport in Peroxisomen

Forscher entdecken Riesenpore in der Membran der Zellorganellen / So gelangen Proteine in gefaltetem Zustand ins Innere

(PresseBox) (Bochum, )
Forscher der Ruhr-Universität Bochum haben in Zusammenarbeit mit Kollegen aus Osnabrück, Bremen und Göttingen eine zweite Riesenpore für den Transport von gefalteten Proteinen in bestimmte Zellorganellen, die Peroxisomen, entdeckt. Eine erste Riesenpore hatte die Gruppe bereits vor fünf Jahren beschrieben. Die Ergebnisse berichtet das Team um Prof. Dr. Ralf Erdmann vom Institut für Biochemie und Pathobiochemie in der Zeitschrift "Cell Reports".

Import von gefalteten Proteinen war lange Zeit ein Rätsel

Peroxisomen sind unter anderem am Abbau von Fettsäuren beteiligt und entschärfen giftiges Wasserstoffperoxid in der Zelle. Sie sind mit zahlreichen Enzymen ausgestattet, die sie aus der Zellflüssigkeit importieren müssen. "Wie Bvwpcwcstus hcstpvh Mzcolctf iggcmbidylqe, bio uhxhr hif Spruzr", bdhl Qmux Piytelm.
