The protein structure of the archaellum, the motor that propels many species of Archaea, the third domain of life, has been characterized for the first time by a team from Lawrence Berkeley National Laboratory and the Max Planck Institute for Terrestrial Microbiology. A ring made of six identical proteins derives energy from hydrolyzing adenosine triphosate and uses this energy to drive shape changes, both assembling and rotating the archaellum's whiplike propeller.
