The motile bacteria are able to move by
WebRecent technological advances, especially in cryo-electron microscopy, have greatly improved our knowledge of the molecular machinery that powers the various forms of bacterial motility. In this Review, we describe the current understanding of the physical and molecular mechanisms that allow bacteria to move around. WebThe motile bacteria can move by flagella. This is possible due to the proton motive force generated which results in the clockwise or anticlockwise motion of the flagella. This is …
