  • PubMed Abstract: 

    F 1 F o ATP synthase functions as a biological generator and makes a major contribution to cellular energy production. Proton flow generates rotation in the F o motor that is transferred to the F 1 motor to catalyze ATP production, with flexible F 1 /F o coupling required for efficient catalysis. F 1 F o 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 F 1 F o 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 ο motor. This highlights the importance of the central rotor for flexible coupling of the F 1 and F o motors and provides further insight into the regulatory mechanism mediated by subunit ε.
