Energy transduction between membranes. TonB, a cytoplasmic membrane protein, can be chemically cross-linked in vivo to the outer membrane receptor FepA

TonB, a cytoplasmic membrane protein, couples cytoplasmic membrane protonmotive force to active transport across the outer membrane of Escherichia coli. In vivo cross-linking studies were initiated to analyze TonB interactions with other cell envelope proteins. Four TonB-specific cross-linked comple...
