THE STRUCTURE OF THE OPEN CONFORMATION OF A FLAVOCYTOCHROME C3 FUMARATE REDUCTASE
Overview
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.
About this Structure
1QO8 is a Single protein structure of sequence from Shewanella frigidimarina. Full crystallographic information is available from OCA.
