E coli atp synthase
WebE. coli ATP synthase State 1c. F 1 F o ATP synthase functions as a biological rotary generator that makes a major contribution to cellular energy production. It comprises two molecular motors coupled together by a central and a peripheral stalk. Proton flow through the F o motor generates rotation of the central stalk, inducing conformational changes WebMay 31, 2000 · The simplest F 0 F 1-type ATP synthase, e.g. that of Escherichia coli, is composed of eight types of subunits present in the stoichiometry α 3 β 3 γδϵ for the …
