Function of proline residues of MotA in torque generation by the flagellar motor of Escherichia coli.

Journal of bacteriology - 1 Jun 1999

Abstract excerpt

Bacterial flagellar motors obtain energy for rotation from the membrane gradient of protons or, in some species, sodium ions. The molecular mechanism of flagellar rotation is not understood. MotA and MotB are integral membrane proteins that function in proton conduction and are believed to form the stator of the motor. Previous mutational studies identified two conserved proline residues in MotA (Pro 173 and Pro...
