TonB interacts with nonreceptor proteins in the outer membrane of Escherichia coli.

Journal of bacteriology - 1 Mar 2002

Abstract excerpt

The Escherichia coli TonB protein serves to couple the cytoplasmic membrane proton motive force to active transport of iron-siderophore complexes and vitamin B(12) across the outer membrane. Consistent with this role, TonB has been demonstrated to participate in strong interactions with both the cytoplasmic and outer membranes. The cytoplasmic membrane determinants for that interaction have been previously...
