2.C.1.4.1
TonB-like protein of 280 aas and 1 N-terminal TMS. It interacts with outer membrane receptor proteins that carry out high-affinity binding and energy-dependent uptake into the periplasmic space of specific substrates. It could act to transduce energy from the cytoplasmic membrane to specific energy-requiring processes in the outer membrane, resulting in the release into the periplasm of ligands bound by these outer membrane proteins.
