Molecular Motors: Turning the ATP motor
Richard L. Cross1
Abstract
A long-standing question regarding ATP synthase — a cellular energy-generator — has been which direction it spins in when generating ATP. Some elegant experiments have revealed the answer.
The ATP synthase not only lays claim to being nature's smallest rotary motor, but also has an extremely important role in providing most of the chemical energy that aerobic and photosynthetic organisms need to stay alive. On page 465 of this issue, Itoh and colleagues1 describe how they used electromagnets to force this motor to rotate and generate chemical energy (adenosine trisphosphate, ATP).
