Archaea swim using a unique motile structure.
Archaea, the third domain of life, use a unique rotating propeller to swim, called the archaellum. Although it functions like a bacterial flagellum, its structure resembles a bacterial Type IV pilus. The protein structure of the archaellum has been characterized for the first time by a team from Lawrence Berkeley National Laboratory and the Max Planck Institute for Terrestrial Microbiology. See newscenter.lbl.gov for more information.
