| Research Abstract |
The bacterial flagellar ATPase complexes, which consist of FliH, FliI and FliJ, associate with the docking platform of the export gate through an interaction between FliH and an export gate protein FlhA, thereby forming the FliI6-FliJ ring complex. A specific interaction of FliJ with FlhA brought about by the FliHX-FliI_6 complex allows the export gate to fully utilize proton motive force across the cytoplasmic membrane to drive flagellar protein export.
