Abstract

Haem-copper oxidases are redox driven proton pumps that couple the reduction of molecular oxygen to water to the vectorial translocation of protons across the membrane. During the last few years our knowledge of the structure and function of the haem-copper oxidases has greatly profited from the X-ray structures of cytochrome c oxidases and site-directed mutagenesis studies on the enzymes. Now, we can design experiments aimed at targeting specific proton pumping mechanism based on these results. We have recently solved the crystal structures of cytochrome c oxidase from Rhodobacter sphaeroides and ubiquinol oxidase from E. coli. These crystals provide a unique opportunity to address the oxygen intermediate structures and the proton gating mechanism, by X-ray protein crystallography.
