Abstract excerpt

PomA, a homolog of MotA in the H+-driven flagellar motor, is an essential component for torque generation in the Na+-driven flagellar motor. Previous studies suggested that two charged residues, R90 and E98, which are in the single cytoplasmic loop of MotA, are directly involved in this process. These residues are conserved in PomA of Vibrio alginolyticus as R88 and E96, respectively. To explore the role of these...
