Subunit epsilon is an intrinsic regulator of the bacterial FoF1-ATP synthase, the ubiquitous membrane-embedded enzyme that utilizes a proton motive force in most organisms to synthesize adenosine triphosphate (ATP). The C-terminal domain of epsilon can extend into the central cavity formed by the alpha and beta subunits, as revealed by the recent X-ray structure of the F1 portion of the Escherichia coli enzyme. This insertion blocks the rotation of the central gamma subunit and, thereby…

The novel FRET donor mNeonGreen is evaluated as a fusion to FoF1-ATP synthase and compare it to the previously used fluorophore EGFP to evaluate the biochemical purification procedures and activity measurements of the fully functional mutant enzyme.
Fast ATP-dependent Subunit Rotation in Reconstituted FoF1-ATP Synthase Trapped in Solution
It is reported that kinetic monitoring of functional rotation can be prolonged from milliseconds to seconds by utilizing an Anti-Brownian electrokinetic trap (ABEL trap), and broad distributions of ATP-dependent catalytic rates were revealed.

Binding of the immunomodulatory drug Bz-423 to mitochondrial FoF1-ATP synthase in living cells by FRET acceptor photobleaching
This work measured uptake and binding of a Cy5-labeled Bz-423 derivative to mitochondrial FoF1-ATP synthase in living yeast cells using FRET acceptor photobleaching microscopy and confirmed the binding of Cy5 to the top of the F1 domain of the enzyme in mitochondria of living Saccharomyces cerevisiae cells.
The nuclear encoded subunits gamma, delta and epsilon from the shrimp mitochondrial F1-ATP synthase, and their transcriptional response during hypoxia
The aim of this study was to characterize the full-length cDNA sequences of three subunits that form the central stalk of the F1 catalytic domain of the ATP synthase of the white shrimp Litopenaeus vannamei and their deduced proteins, which confirm their functional structures and specific characteristics from the cognate complex of ATP synthases.


Movements of the epsilon-subunit during catalysis and activation in single membrane-bound H(+)-ATP synthase.
It is concluded that the active-inactive transition was associated with a conformational change of epsilon within the central stalk of F0F1-ATP synthases, and the three states of the inactive enzyme were unequally populated.
Crystal structure of the epsilon subunit of the proton-translocating ATP synthase from Escherichia coli.
BACKGROUND Proton-translocating ATP synthases convert the energy generated from photosynthesis or respiration into ATP. These enzymes, termed F0F1-ATPases, are structurally highly conserved. In

The position of the a subunit of the membrane-integral F0 sector of Escherichia coli ATP synthase was investigated, finding that this relationship provides stability to the membrane interface between a and b2, allowing it to withstand the torque imparted by the rotor during ATP synthesis as well as ATP hydrolysis.

Mechanism of Inhibition by C-terminal α-Helices of the ϵ Subunit of Escherichia coli FoF1-ATP Synthase*
The results suggest that the C-terminal domain of the ϵ subunit of EFoF1 slows multiple elementary steps in both the ATP synthesis/hydrolysis reactions by restricting the rotation of the γ subunit.
