Maschinen des Lebens arbeiten auch ohne Wasser

Neutronenexperimente erklären Funktionsweise von Protein-Polymer-Hybriden

(PresseBox) (Jülich, )
Ohne Wasser können Proteine, die Maschinen der Zellen, ihre vielfältigen Aufgaben nicht erfüllen - dieser Grundsatz galt über Jahre. Doch 2010 entdeckten Forscher, dass Hybride aus Proteinen und Polymeren auch ohne Wasser biologisch aktiv sein können. Solche Hybride sind für industrielle Prozesse von Interesse, bei denen Wasser nicht verwendet werden kann. Warum Proteine auch ohne Wasser arbeiten, zeigt jetzt ein internationales Forscherteam mit Hilfe von Neutronenexperimenten. Die Ergebnisse sind auf den Webseiten der internationalen Fachzeitschrift "JACS" nachzulesen (DOI: 10.1021/ja303894g).

Proteine sind winzige biologische Maschinen. Sie katalysieren lebenswichtige Prozesse in tierischen und pflanzlichen Zellen, geben Geweben Halt oder synthetisieren Stoffe pcn Cruaogh gyo Mxqenhupc.
