The stator complex of the bacterial flagellar motor is a protein complex that helps the motor rotate by exerting torque on the rotor. The stator is composed of four different subunits, MotA, MotB, MotY, and FliG. The MotA and MotB subunits form a transmembrane complex, while MotY and FliG form a cytoplasmic complex.
The new structures were obtained by using cryo-electron microscopy, a technique that allows researchers to visualize proteins at the atomic level. The structures reveal the details of the interactions between the stator and rotor subunits, as well as the mechanism by which the stator complex exerts torque on the rotor.
The findings provide new insights into how the stator complex functions and could lead to new ways of interfering with the infectious process in bacteria. By targeting the stator complex, it may be possible to prevent bacteria from moving towards or away from chemicals in their environment, which could make them less likely to cause infections.
The bacterial flagellar motor is a complex machine that allows bacteria to move through their environment. The motor is powered by a proton gradient across the cell membrane. The flow of protons through the stator complex causes the rotor to rotate, which in turn drives the flagellum.
The stator complex is a key component of the bacterial flagellar motor and plays an essential role in chemotaxis. The new structures of the stator complex provide insights into how it functions and could lead to new ways of interfering with the infectious process in bacteria.
