The position of the a subunit of the membrane-integral F0 sector of Escherichia coli ATP synthase was investigated by single molecule fluorescence resonance energy transfer studies utilizing a fusion of enhanced green fluorescent protein to the C terminus of the a subunit and fluorescent labels attached to specific positions of the ϵ or γ subunits. Three fluorescence resonance energy transfer levels were observed during rotation driven by ATP hydrolysis corresponding to the three resting…

Structural Asymmetry and Kinetic Limping of Single Rotary F-ATP Synthases

The enzyme’s rotary progression during ATP hydrolysis is monitored by three single-molecule techniques: fluorescence video-microscopy with attached actin filaments, Förster resonance energy transfer between pairs of fluorescence probes, and a polarization assay using gold nanorods, and it is found that one dwell in the three-steppedrotary progression lasting longer than the other two by a factor of up to 1.6.

Regulatory conformational changes of the epsilon subunit in single FRET-labeled FoF1-ATP synthase

Labeling the C-terminal domain of epsilon and the gamma subunit specifically with two different fluorophores for single-molecule Foerster resonance energy transfer (smFRET) allowed monitoring of the conformation of ePSilon in the reconstituted enzyme in real time.

Regulatory conformational changes of the Ɛ subunit in single FRET-labeled F0F1-ATP synthase

An experimental system is developed that can reveal conditions under which ε inhibits the holoenzyme FoF1-ATP synthase in vitro and labels the C-terminal domain of ε and the γ subunit specifically with two different fluorophores for single-molecule Förster resonance energy transfer (smFRET).

Escherichia coli F1Fo-ATP Synthase with a b/δ Fusion Protein Allows Analysis of the Function of the Individual b Subunits*

It is shown that it is possible to generate a functional E. coli ATP synthase containing a b/δ fusion protein, which allowed the analysis of the roles of the individual b subunits.

Analyzing conformational changes in single FRET-labeled A1 parts of archaeal A1AO-ATP synthase

The lifetimes of fluorescence donor and acceptor dyes are analyzed to distinguish between smFRET signals of conformational changes and potential artefacts to prevent wasteful ATP hydrolysis.

The regulatory switch of F1-ATPase studied by single-molecule FRET in the ABEL trap

This work labels F1 specifically with two fluorophores to monitor the C-terminus of the ε subunit by Förster resonance energy transfer and compares FRET changes in single F1 and FRET histograms for different biochemical conditions to evaluate the proposed regulatory mechanism.

Diffusion properties of single FoF1-ATP synthases in a living bacterium unraveled by localization microscopy

FoF1-ATP synthases in Escherichia coli (E. coli) bacteria are membrane-bound enzymes which use an internal protondriven rotary double motor to catalyze the synthesis of adenosine triphosphate (ATP).

Structure of the γ–ɛ complex of ATP synthase

ATP synthases (F1Fo-ATPases) use energy released by the movement of protons down a transmembrane electrochemical gradient to drive the synthesis of ATP, the universal biological energy currency.

A Unique Resting Position of the ATP-synthase from Chloroplasts*

The three-dimensional map provides a scaffold for fitting in the known atomic structures of various subunits and sub-complexes, and suggests that the oxidized, non-activated ATP-synthase from chloroplasts adopts a unique resting position.

Both Rotor and Stator Subunits Are Necessary for Efficient Binding of F1 to F0 in Functionally Assembled Escherichia coli ATP Synthase*

In F1F0-ATP synthase, the subunit b2δ complex comprises the peripheral stator bound to subunit a in F0 and to the α3β3 hexamer of F1, which indicates that both rotor and stator components of F0 contribute to F1 binding affinity in the assembled holoenzyme.

Movements of the ε‐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 ε within the central stalk within F0F1‐ATP synthases, which catalyze proton transport‐coupled ATP synthesis in bacteria, chloroplasts, and mitochondria.

Aqueous access pathways in subunit a of rotary ATP synthase extend to both sides of the membrane

The role of subunit a in promoting proton translocation and rotary motion in the Escherichia coli F1Fo ATP synthase is poorly understood and substitution into the second and fifth TMHs of sub unit a and chemical modification with Ag+ and N-ethylmaleimide are carried out to define the aqueous accessibility of residues along these helices.

The "second stalk" of Escherichia coli ATP synthase: structure of the isolated dimerization domain.

A model is constructed for the b(62-122) dimer in which the two helices form a coiled coil with a right-handed superhelical twist, which is expected for the proposed two-stranded, right- handed coiled-coil structure.

This essay will review recent studies on the Escherichia coli F(o) sector and propose a model that mechanically links helix rotation within a single subunit c to the incremental 30 degrees rotation of the c(12) oligomer.
