In this paper the authors emphasise that the proton translocating ATP synthase from thiol‐modulated chloroplasts and two cyanobacterial strains has a coupling ratio of 4 protons per ATP synthesised or hydrolysed. This ratio is determined by several thermodynamic studies at equilibrium between phosphate potential (ΔG p) and proton gradient ( ), and is confirmed by measurement of proton flux during ATP hydrolysis. Ratios lower than 4 H+/ATP that have been published in the past have predominantly… Expand
Comparison of the H+/ATP ratios of the H+-ATP synthases from yeast and from chloroplast
TLDR
The data show that the thermodynamic H+/ATP ratio depends on the stoichiometry of the c-subunit, although it is not identical to the c/β ratio. Expand
Stoichiometry of Energy Coupling by Proton-Translocating ATPases: A History of Variability
TLDR
Recent discoveries concerning the structure of the ATPases, their assembly and the stoichiometry of their numerous subunits, particularly the proton-carrying proteolipid (subunit c) of the FO and V0 sectors, have shed new light on this question and raise the possibility of variable coupling ratios modulated by variable proteolIPid stoichiometries.

It was found that methanol, heat treatment or dithiothreitol did not activate ATP hydrolysis in Synechococcus 6716 and the difference in activation requirements of both ATP synthases resides in a different arrangement of the γ and e subunits. Expand

TLDR
Results suggest that ATP-Pi exchange resembles photophosphorylation, and it is nucleoside diphosphate from the medium that is phosphorylated during exchange, which means that ATP synthesis from medium ADP and Pi takes place at the expense of the pH gradient generated by ATP hydrolysis. Expand
