Step size of the rotary proton motor in single FoF1-ATP synthase from a thermoalkaliphilic bacterium by DCO-ALEX FRET
Eva Hammann, Andrea Zappe, Stefanie Keis +5
Thermophilic enzymes can operate at higher temperatures but show reduced activities at room temperature. They are in general more stable during preparation and, accordingly, are co…
Monitoring transient elastic energy storage within the rotary motors of single FoF1-ATP synthase by DCO-ALEX FRET
Stefan Ernst, Monika G. Dueser, Nawid Zarrabi +1
The enzyme FoF1-ATP synthase provides the 'chemical energy currency' adenosine triphosphate (ATP) for living cells. Catalysis is driven by mechanochemical coupling of subunit rotat…
Subunit rotation in a single FoF1-ATP synthase in a living bacterium monitored by FRET
Karin Seyfert, Takuya Oosaka, Hideyuki Yaginuma +4
FoF1-ATP synthase is the ubiquitous membrane-bound enzyme in mitochondria, chloroplasts and bacteria which provides the 'chemical energy currency' adenosine triphosphate (ATP) for…
Drug transport mechanism of P-glycoprotein monitored by single molecule fluorescence resonance energy transfer
Stefan Ernst, Brandy Verhalen, Nawid Zarrabi +2
In this work we monitor the catalytic mechanism of P-glycoprotein (Pgp) using single-molecule fluorescence resonance energy transfer (FRET). Pgp, a member of the ATP binding casset…
36 degree step size of proton-driven c-ring rotation in FoF1-ATP synthase
Monika G. Dueser, Nawid Zarrabi, Daniel J. Cipriano +4
Synthesis of the biological "energy currency molecule" adenosine triphosphate ATP is accomplished by FoF1-ATP synthase. In the plasma membrane of Escherichia coli, proton-driven ro…
Simultaneous monitoring of the two coupled motors of a single FoF1-ATP synthase by three-color FRET using duty cycle-optimized triple-ALEX
N. Zarrabi, S. Ernst, M. G. Dueser +5
FoF1-ATP synthase is the enzyme that provides the 'chemical energy currency' adenosine triphosphate, ATP, for living cells. The formation of ATP is accomplished by a stepwise inter…
