Abstract excerpt

Shewanella oneidensis MR-1 possesses two different stator units to drive flagellar rotation, the Na+ -dependent PomAB stator and the H+ -driven MotAB stator, the latter possibly acquired by lateral gene transfer. Although either stator can independently drive swimming through liquid, MotAB-driven motors cannot support efficient motility in structured environments or swimming under anaerobic conditions. Using...
