abstract：:F(0)F(1)-ATPase is a rotary molecular motor. It is well known that the rotary torque is generated by ATP hydrolysis in F(1) but little is known about how it produces the proton-motive force (PMF) in F(0). Here a cross-linking approach was used to estimate the rotary torque produced by PMF. Three mutant E. coli strains...
