Dynamism and regulation of the stator, the energy conversion complex of the bacterial flagellar motor.

摘要: Many motile bacteria swim by rotating their motility organ, the flagellum. Rotation of flagellum is driven a motor at its base, and torque generated rotor–stator interaction coupled with specific ion flow through channel in stator. Because stator works as an energy-conversion complex motor, understanding functional mechanism critically important. But characterization has been hampered due to difficulty isolating from membrane. Recently, successful new approaches for studying have reported that reveal novel properties. Two those, visualization vivo behavior units using fluorescently tagged proteins structure-guided analyses soluble region stator, are summarized this short review.
