WebThe bacterial flagellar motor is a reversible rotary nano-machine, about 45 nm in diameter, embedded in the bacterial cell envelope. It is powered by the flux of H+ or Na+ ions across the cytoplasmic membrane driven by an electrochemical gradient, the proton-motive force or the sodium-motive force. WebSep 1, 2024 · Flagella protein fibers serve as conserved structural components for bacterial mobility. Similar to other naturally occurring assemblies such as collagens, elastin, silk, keratin, amyloid beta and prions, they are naturally assembled on the bacterial surface with a similar linear morphology [ [19], [20], [21], [22], [23], [24] ].
