Nature's Rotary Electromotors

Abstract
Cells are packed full of molecular motors that carry out a plethora of different functions. In their Perspective, Junge and Nelson discuss two recent studies ( Meier et al., Murata et al.) that shed light on the workings of rotary electromotors, one designed to drive the synthesis of the energy carrier molecule ATP, the other to pump sodium cations at the expense of ATP hydrolysis
