| Type | Family |
| Description | Members of this family are Gram-negative bacterial inner membrane proteins, generally designated ExbD, related to the TolR . Members are always found next to a protein designated ExbB ( ), which is related to the TolQ family (). ExbD and ExbB together form a proton channel through which they can harness the proton-motive force to energize TonB, which in turn energizes TonB-dependent receptors in the outer membrane. TonB-dependent receptors with known specificity tend to import siderophores or vitamin B12. A TonB system and Tol-Pal system often will co-exist in a single bacterial genome. |
