摘 要:The membrane-bound H+-ATPase of E. coil consisted of two parts: F1 and F0. Purified ε subunit of F1 strongly inhibited F1 but showed no inhibitory effect in reconstituted F1F0. In 1987, G. B. Cox et al. isolated a mutant of ε subunit, and two partial revertants, Their experiments showed that F1F0 complex was still formed in the mutant. The hydrolytic activity and transmembrane proton transfer ability were all impaired in the
