Function of protonatable residues in the flagellar motor of Escherichia coli: a critical role for Asp 32 of MotB.

Journal of bacteriology - 1 May 1998

Zhou J, Sharp L L, Tang H L, Lloyd S A, Billings S, Braun T F, Blair D F

Abstract excerpt

Rotation of the bacterial flagellar motor is powered by a transmembrane gradient of protons or, in some species, sodium ions. The molecular mechanism of coupling between ion flow and motor rotation is not understood. The proteins most closely involved in motor rotation are MotA, MotB, and FliG. MotA and MotB are transmembrane proteins that function in transmembrane proton conduction and that are believed to form...
