Genetic suppression demonstrates interaction of TonB protein with outer membrane transport proteins in Escherichia coli.

Abstract

Energy-coupled reactions of the Escherichia coli outer membrane transport proteins BtuB and Cir require the tonB product. Some point mutations in a region of btuB and cir that is highly conserved in TonB-dependent transport proteins led to loss of TonB-coupled uptake of vitamin B12 and colicin Ia, whereas binding was unaffected. Most other point mutations… (More)
