Functional transfer of an essential aspartate for the ion-binding site in the stator proteins of the bacterial flagellar motor.

Journal of molecular biology - 2 Apr 2010

Terashima Hiroyuki, Kojima Seiji, Homma Michio

Abstract excerpt

Rotation of the bacterial flagellar motor exploits the electrochemical potential of the coupling ion (H(+) or Na(+)) as its energy source. In the marine bacterium Vibrio alginolyticus, the stator complex is composed of PomA and PomB, and conducts Na(+) across the cytoplasmic membrane to generate...
