| Abstract |
Many bacteria can swim using their flagella, which are filamentous organelles that extend from the cell surface. The flagellar motor is energized by either a proton (H(+)) or sodium ion (Na(+)) as the motive force. MotAB-type stators use protons, whereas MotPS- and PomAB-type stators use Na(+) as the coupling ions. Recently, alkaliphilic Bacillus alcalophilus was shown to use potassium ions (K(+)) and rubidium ions (Rb(+)) for flagellar rotation, and the flagellar motor from Paenibacillus sp. TCA-20 uses divalent cations such as magnesium ions (Mg(2+)), calcium ions (Ca(2+)), and strontium ions (Sr(2+)) for coupling. In this chapter, we focus on how to identify the coupling ions for flagellar rotation of alkaliphilic Bacillus and Paenibacillus species. |
