Atovaquone, a substituted hydroxynaphthoquinone, is a potent antimalarial drug that acts by inhibiting the parasite's mitochondrial cytochrome bc1 complex (cyt bc1). Mutations in cyt bc1 confer atovaquone resistance. Here we describe the X-ray structure of mitochondrial cyt bc1 from Saccharomyces cerevisiae with atovaquone bound in the catalytic Qo site, at 3.0-A resolution. A polarized H-bond to His181 of the Rieske protein in cyt bc1 traps the ionized hydroxyl group of the drug. Side chains of highly conserved cytochrome b residues establish multiple non-polar interactions with the napththoquinone group, whereas less-conserved residues are in contact with atovaquone's cyclohexyl-chlorophenyl tail. Our structural analysis reveals the molecular basis of atovaquone's broad target spectrum, species-specific efficacies and acquired resistances, and may aid drug development to control the spread of resistant parasites. | |||
