The dynamic response of the bacterial flagellar motor to its direct intracellular input signal

Alina M. Vrabioiu, Basarab Gabriel Hosu, Aravinthan D. T. Samuel

This paper demonstrates that activation of 1-3 CheY-P molecules is sufficient to switch the bacterial flagellar motor from CCW to CW, resolving a long-standing paradox about chemotactic sensitivity.

Torque-generating units of the bacterial flagellar motor are rotary motors

Basarab Gabriel Hosu, Alina M. Vrabioiu, Aravinthan D. T. Samuel

The paper demonstrates that bacterial flagellar motor stator units are rotary motors, with MotA pentamers rotating faster than the rotor, revealing a gear-like mechanism.
