Succinate dehydrogenase oxidizes succinate and reduces ubiquinone using a flavin adenine dinucleotide cofactor and iron-sulfur clusters to transport electrons. A model of the quaternary structure of the tetrameric Saccharomyces cerevisiae succinate dehydrogenase was constructed based on the crystal structures of the Escherichia coli succinate dehydrogenase, the E. coli fumarate reductase, and the Wolinella succinogenes fumarate reductase. One FAD and three iron-sulfur clusters were docked into the Sdh1p and Sdh2p catalytic dimer. One b-type heme and two ubiquinone or inhibitor analog molecules were docked into the Sdh3p and Sdh4p membrane dimer. The model is consistent with numerous experimental observations. The calculated free energies of inhibitor binding are in excellent agreement with the experimentally determined inhibitory constants. Functionally important residues identified by mutagenesis of the SDH3 and SDH4 genes are located near the two proposed quinone-binding sites, which are separated by the heme. The proximal quinone-binding site, located nearest the catalytic dimer, has a considerably more polar environment than the distal site. Alternative low energy conformations of the membrane subunits were explored in a molecular dynamics simulation of the dimer embedded in a phospholipid bilayer. The simulation offers insight into why Sdh4p Cys-78 may be serving as the second axial ligand for the heme instead of a histidine residue. We discuss the possible roles of heme and of the two quinone-binding sites in electron transport."xsd:string |
