Residues of the cytoplasmic domain of MotA essential for torque generation in the bacterial flagellar motor.

Abstract

The MotA protein of Escherichia coli is a component of the flagellum that functions, together with MotB, in transmembrane proton conduction. MotA and MotB are believed to form the stator of the flagellar motor. They are integral membrane proteins; MotA has a large (ca 22 kDa) domain in the cytoplasm, and MotB a much smaller one (ca 3 kDa). Recent work… (More)
