Wo und wie beginnt die Übersetzung des genetischen Codes?

Neuer Mechanismus bei Archaea entdeckt

(PresseBox) (Frankfurt am Main, )
Wie der genetische Code der Lebewesen in Proteine übersetzt wird, wie also die so genannte Translation funktioniert, das glaubte man seit Jahren perfekt verstanden zu haben. Doch der Teufel steckt im Detail, fand jetzt die Arbeitsgruppe um den Frankfurter Genetiker Prof. Jörg Soppa heraus. An Archaea, die neben den zellkernlosen Bakterien und zellkerntragenden Organismen wie Tieren, Pilzen und Pflanzen (Eucaryota) die dritte Klasse von Lebewesen bilden, fanden die Forscher eine neue Art der so genannten Translationsinitiation. Hinter diesem Begriff verbirgt sich der Mechanismus, der einem Ribosom anzeigt, an welcher Stelle der Code für eine Proteinsequenz auf der mRNA beginnt.
