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 with and as ligands. Active as Succinate dehydrogenase, with EC number 1.3.99.1 Known structural/functional Sites: , , , , , , , , and . Full crystallographic information is available from OCA.
