Zellforscher identifizieren neuen Biosynthese-Mechanismus

PUMa: Elektronenstrom führt zu stabilen Eisen-Schwefel-Proteinen

(PresseBox) (Marburg, )
Wissenschaftler der Philipps-Universität Marburg (PUMa) haben einen Mechanismus aufgeklärt, der Zellen höherer Lebewesen in die Lage versetzt, Enzyme mit Eisen-Schwefel-Zentren herzustellen. Die Wissenschaftler um Professor Dr. Roland Lill und Privatdozent Dr. Antonio Pierik berichten in der aktuellen Online-Ausgabe der Fachzeitschrift "Nature Chemical Biology" über ihre Ergebnisse.

"Enzyme mit Eisen-Schwefel-Clustern sind unersetzlich für zahlreiche essenzielle Lebensprozesse", erläutert Lill, Senior-Autor der Studie. Beispiele hierfür sind insbesondere die Energiegewinnung in den Mitochondrien, die Proteinherstellung an Ribosomen, die Vervielfältigung der Erbsubstanz DNA sowie deren Reparatur nach Schädigungen. "Eisen-Schwefelhaltige Proteine finden sich daher sowohl bei Bakterien als auch in den Zellen von höheren Lebewesen owa glhfmf Ttrebqfe", uviowas Cimjret Ngrbqy, "mcak qobn fhv Qrifgjoe kix Sovskf".
