CC   -!- FUNCTION: Interacts with outer membrane receptor proteins that carry
CC       out high-affinity binding and energy dependent uptake into the
CC       periplasmic space of specific substrates. It could act to transduce
CC       energy from the cytoplasmic membrane to specific energy-requiring
CC       processes in the outer membrane, resulting in the release into the
CC       periplasm of ligands bound by these outer membrane proteins (By
CC       similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000250}; Single-pass
CC       membrane protein {ECO:0000250}; Periplasmic side {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the TonB family. {ECO:0000305}.
