Citation | Journal: Commun Biol / Year: 2023Title: Changes within the central stalk of E. coli FF ATP synthase observed after addition of ATP. Authors: Meghna Sobti / Yi C Zeng / James L Walshe / Simon H J Brown / Robert Ishmukhametov / Alastair G Stewart / ![]() Abstract: FF ATP synthase functions as a biological generator and makes a major contribution to cellular energy production. Proton flow generates rotation in the F motor that is transferred to the F motor to ...FF ATP synthase functions as a biological generator and makes a major contribution to cellular energy production. Proton flow generates rotation in the F motor that is transferred to the F motor to catalyze ATP production, with flexible F/F coupling required for efficient catalysis. FF ATP synthase can also operate in reverse, hydrolyzing ATP and pumping protons, and in bacteria this function can be regulated by an inhibitory ε subunit. Here we present cryo-EM data showing E. coli FF ATP synthase in different rotational and inhibited sub-states, observed following incubation with 10 mM MgATP. Our structures demonstrate how structural transitions within the inhibitory ε subunit induce torsional movement in the central stalk, thereby enabling its rotation within the F motor. This highlights the importance of the central rotor for flexible coupling of the F and F motors and provides further insight into the regulatory mechanism mediated by subunit ε. | |||||||||||||||||||||||||||||||||||||||
