MotA is a membrane protein that forms the stator element of the flagellar motor complex together with MotB with 5:2 stoichiometry, which couples ion flow across the cytoplasmic membrane to generate torque, and thus, it is required for rotation of the flagellar motor. This domain contains conserved torque-generating charged residues at the C-terminal [1] and is adjacent Pfam:PF01618, which represents MotA TMH3 and TMH4.
