The MotA protein of E. coli is a proton-conducting component of the flagellar motor.

Cell - 9 Feb 1990

Blair D F, Berg H C

Abstract excerpt

A number of mutants of motA, a gene necessary for flagellar rotation in E. coli, were isolated and characterized. Many mutations were dominant, owing to competition between functional and nonfunctional MotA for a limited number of sites on the flagellar motor. A new class of mutant was discovered in which flagellar torque is normal at low speeds but reduced at high speeds. Hydrogen isotope effects on these...
