Zooming in on ATP hydrolysis in F1.
We summarize our current view of the reaction mechanism in F(1)-ATPase as it has emerged from experiment, theory, and computational studies over the last several years. ATP catalysis in the catalytic binding pockets of F(1) takes place without the release of any significant free energy and is efficiently driven by the combined action of two water molecules utilizing a so-called protein-relay mechanism. The chemical reaction itself is controlled by the spatial position of a key arginine residue.
