Why is the mechanical efficiency of F(1)-ATPase so high?
The experimentally measured mechanical efficiency of the F(1)-ATPase under viscous loading is nearly 100%, far higher than any other hydrolysis-driven molecular motor (Yasuda et al., 1998). Here we give a molecular explanation for this remarkable property.
