Tryptophan-scanning mutagenesis of MotB, an integral membrane protein essential for flagellar rotation in Escherichia coli.

Biochemistry - 18 Jul 1995

Sharp L L, Zhou J, Blair D F

Abstract excerpt

The MotB protein of Escherichia coli is an essential component of the flagella that functions together with the MotA protein in transmembrane proton conduction. MotB has a single hydrophobic segment that spans the membrane. In order to determine which parts of the membrane-spanning segment can tolerate the introduction of a large, hydrophobic side chain, single Trp residues were substituted into many consecutive...
