cube: LytB, an enzyme containing a [4Fe‐4S] cluster, catalyzes the last step of the methylerythritol phosphate pathway, a target for antibacterial and antiparasitic drugs. Field‐dependent Mössbauer spectroscopy showed that the unique fourth iron atom of the [4Fe‐4S] cluster coordinates to the hydroxy group of the substrate (see picture) and to the amino and thiol moieties of two potent inhibitor substrate
