Graphical Abstract

Anti-Terminator – Aufstand der Moleküle: Die Überexpression eines Antiterminator-Gens (nusG) in Clostridium cellulolyticum induziert die Biosynthese des neuartigen Antibiotikums Closthioamid und zahlreicher verwandter Thioamide. Dies ist die erste erfolgreiche genetische Manipulation eines Anaerobiers zur Aktivierung eines kryptischen Reaktionspfads. Synthetische Sonden liefern zudem Einblicke in die biogenetische Verwandtschaft der raren Thioamid-Metabolite.
