Conformational dynamics of the rotary subunit F in the A3B3DF complex of Methanosarcina mazei Gö1 A-ATP synthase monitored by single-molecule FRET

In archaea the A1AO ATP synthase uses a transmembrane electrochemical potential to generate ATP, while the soluble A1 domain (subunits A3B3DF) alone can hydrolyse ATP. The three nucleotide-binding AB pairs form a barrel-like structure with a central orifice that hosts the rotating central stalk subu...
