Flagellar motor (IMAGE)
Caption
The flagellar motor is formed of a series of rings bound by proteins. The scientists looked specifically at the C-ring (blue), which is present inside the bacterial cytoplasm. The C-ring is formed of FliG, FliN and FliM proteins. The scientists found that during the switch from counterclockwise to clockwise rotation, part of FliG moves, exposing its charged residues so they interact with the stator.
