Mutant MotB proteins in Escherichia coli.

Journal of bacteriology - 1 Jul 1991

Blair D F, Kim D Y, Berg H C

Abstract excerpt

The MotB protein of Escherichia coli is an essential component in each of eight torque generators in the flagellar rotary motor. Based on its membrane topology, it has been suggested that MotB might be a linker that fastens the torque-generating machinery to the cell wall. Here, we report the isolation and characterization of a number of motB mutants. As found previously for motA, many alleles of motB were...
