Werkbank für Antibiotika

Marburger Wissenschaftler erforschen, wie bioaktive Peptide synthetisiert werden

(PresseBox) (Marburg, )
Biochemiker von der Philipps-Universität haben die Struktur einer molekularen Werkbank aufgeklärt, mit der Bakterien eine Vielzahl von Peptiden herstellen, darunter auch wichtige Antibiotika und Fungizide. Wie die Wissenschaftler um Professor Dr. Lars-Oliver Essen und Professor Dr. Mohamed A. Marahiel in der aktuellen Online-Ausgabe von "Science" berichten, bilden die untersuchten Moleküle eine Plattform, auf der Aminosäuren zu Ketten zusammengebaut werden. "Die Kenntnis dieses Mechanismus' eröffnet neue Möglichkeiten für die Produktion von Arzneimitteln", erläutert Professor Essen.

Peptide sind kurze Ketten aus Aminosäuren, im Unterschied zu den langkettigen Proteinen. Mikroorganismen können Peptide in weitaus größerer struktureller Vielfalt produzieren als Proteine, für deren
