    • Proton-translocating ATP synthases convert the energy generated from photosynthesis or respiration into ATP. These enzymes, termed F0F1-ATPases, are structurally highly conserved. In Escherichia coli, F0F1-ATPase consists of a membrane portion, F0, made up of three different polypeptides (a, b and c) and an F1 portion comprising five different polypeptides in the stoichiometry alpha 3 beta 3 gamma delta epsilon ...

    Proton-translocating ATP synthases convert the energy generated from photosynthesis or respiration into ATP. These enzymes, termed F0F1-ATPases, are structurally highly conserved. In Escherichia coli, F0F1-ATPase consists of a membrane portion, F0, made up of three different polypeptides (a, b and c) and an F1 portion comprising five different polypeptides in the stoichiometry alpha 3 beta 3 gamma delta epsilon. The minor subunits gamma, delta and epsilon are required for the coupling of proton translocation with ATP synthesis; the epsilon subunit is in close contact with the alpha, beta, gamma and c subunits. The structure of the epsilon subunit provides clues to its essential role in this complex enzyme.
