ABC (ATP-binding cassette) transporters are arguably the most important family of ATP-driven transporters in biology. Despite considerable effort and advances in determining the structures and physiology of these transporters, their fundamental molecular mechanisms remain elusive and highly controversial. How does ATP hydrolysis by ABC transporters drive(More)
Steady-state ATP hydrolysis in the F1-ATPase of the F(O)F1 ATP synthase complex involves rotation of the central gamma subunit relative to the catalytic sites in the alpha3beta3 pseudo-hexamer. To understand the relationship between the catalytic mechanism and gamma subunit rotation, the pre-steady-state kinetics of Mg x ATP hydrolysis in the soluble(More)
