ATP-dependent rotation of mutant ATP synthases defective in proton transport.

Abstract

During ATP hydrolysis, the gammaepsilon c10 complex (gamma and epsilon subunits and a c subunit ring formed from 10 monomers) of F0F1 ATPase (ATP synthase) rotates relative to the alpha3beta3delta ab2 complex, leading to proton transport through the interface between the a subunit and the c subunit ring. In this study, we replaced the two pertinent residues… (More)
