Functional Description

 MotA and MotB comprise the stator element of the flagellar motor complex. Required for the rotation of the flagellar motor. Probably a linker that fastens the torque- generating machinery to the cell wall. Overexpression of this protein with MotA improves motility in a yhjH disruption, (a c-di- GMP phosphodiesterase) suggesting there is an interaction (direct or indirect) between the c-di-GMP-binding flagellar brake protein YcgR and the flagellar stator.
