Abstract excerpt

Labile [4Fe-4S](2+) clusters found at the active sites of many dehydratases are susceptible to damage by univalent oxidants that convert the clusters to an inactive [3Fe-4S](1+) form. Bacteria repair damaged clusters in a process that does not require de novo protein synthesis or the Isc and Suf cluster assembly pathways. The current study investigates the participation of the bacterial frataxin ortholog CyaY and...
