Mutations in the MotA protein of Escherichia coli reveal domains critical for proton conduction.

Journal of molecular biology - 20 Oct 1991

Blair D F, Berg H C

Abstract excerpt

The MotA protein of Escherichia coli is an essential component of the torque-generating units that drive the flagellar rotary motor. A variety of evidence indicates that MotA is involved in transmembrane proton conduction. We have now mapped a number of MotA mutants, focusing primarily on those previously shown to be dominant. Fifty-six mutations (all dominant), each causing severe or complete impairment of...
