The second stalk: the delta-b subunit connection in ECF1F0.
The ATP synthase F1F0 is the smallest molecular motor yet studied. ATP hydrolysis drives the rotary motion of the primary stalk subunits gamma and epsilon relative to the alpha 3 beta 3 part of F1. Evidence is reviewed to show that the delta and b subunits provide a second stalk that can act as a stator to facilitate these rotational movements.
