Störung in der Proteinfabrik

Wie Antibiotika die Proteinsynthese im Ribosom lahm legen

(PresseBox) (Frankfurt am Main, )
Die Protein-Biosynthese ist einer der wichtigsten Prozesse in jeder lebenden Zelle. Dabei wird der genetische Code in eine Kette von Aminosäuren übersetzt, die sich dann zu der dreidimensionalen Struktur eines Proteins faltet. Ist die Protein-Biosynthese gestört, gerät die Maschinerie des Lebens ins Stocken. Daher ist sie ein beliebtes Angriffsziel anti-mikrobieller Wirkstoffe, die unerwünschte Krankheitserreger abtöten sollen. Und so greifen die meisten der neu entwickelten Antibiotika genau in diesen komplexen Prozess am Ribosom ein. Wissenschaftlern des Exzellenzclusters Makromolekulare Komplexe an der Goethe Universität Frankfurt ist es nun erstmals gelungen, das Andocken von Antibiotika an einem neuen Ort der bakteriellen Proteinfabrik, dem
