Structure
TonB and ExbD bind to ExbB in a protein complex that prevents the degradation of the TonB protein. TonB and ExbD are anchored to the cytoplasmic membrane via their N-terminal hydrophobic sequences, with the rest of the protein complex extending into the periplasmic space, allowing for interaction with outer membrane proteins.[1]
The C-terminal of TonB (see C-Terminal Domain of TonB).
Function
The activity of TonB is determined by the presence of ExbB and ExbD. [1]
