Fumarate reductases and succinate dehydrogenases play central roles in the metabolism of eukaryotic and prokaryotic cells. A recent medium resolution structure of the Escherichia coli fumarate reductase (Frd) has revealed the overall organization of the membrane-bound complex. Here we present the first high resolution X-ray crystal structure of a water-soluble bacterial fumarate reductase in an open conformation. This structure reveals a mobile domain that modulates substrate access to the active site and provides new insights into the mechanism of this widespread and important family of FAD-containing respiratory proteins.
