Proteine - die molekularen Maschinen unserer Zellen - besitzen einen entscheidenden Unterschied gegenüber technischen Maschinen, wie wir sie aus unserem Alltag kennen. Je nach Aufgabe, die sie erfüllen, können Proteine ihre Struktur innerhalb winzigster Bruchteile von Sekunden anpassen. Aber auch bei der Zusammenarbeit mit anderen Proteinen zählt die äußere Form. Anders als bisher angenommen, werden jedoch nicht alle Proteine zunächst von ihrem Partner passgenau zurechtgebogen. Es gibt Proteine, die ihre Struktur ständig ändern und dabei auch ganz ohne fremde Hilfe "in Form" kommen. Dies hat ein Wissenschaftler-Team vom Göttinger Max-Planck-Institut für biophysikalische Chemie herausgefunden, indem sie einen wahren Verwandlungskünstler unter mvd Oogrhiumb ncziepuxuebr - jea Ecjhascoa.
