Graphical Abstract

Ein faszinierender Kubus: LytB, ein Enzym mit einem [4Fe-4S]-Cluster, katalysiert den letzten Schritt des Methylerythritolphosphatweges, eines Targets für antibakterielle und antiparasitäre Wirkstoffe. Feldabhängige Mößbauer-Spektroskopie zeigte, dass das besondere vierte Eisenatom des [4Fe-4S]-Clusters an die Hydroxygruppe des Substrats (siehe Bild) sowie die Amin- und die Thiolfunktion der beiden Substratanaloga bindet, die gute Inhibitoren sind.
