The TolQR complex uses the proton motive force to regulate TolA conformation and its interaction with the outer membrane Pal lipoprotein. It has been proposed that an ion …TolQ structurally most resembles ExbB with three core transmembrane helices (T 1-3) and three accessory helices (A 1-3) (SI Appendix, Fig. S4 C and F). The position of conserved Thr (TolQ/ExbB/MotA) and Asp (TolR/ExbD/MotB) residues proposed to be involved in the proton transduction pathway is also structurally conserved across …TolA, TolQ, and TolR proteins form the IM complex of the Tol–Pal system, a proton motive force (PMF)-dependent molecular motor conserved in gram-negative bacteria (Fig. 1 A). The TolQ–TolR motor is evolutionary related to the ExbB–ExbD motor of the Ton system, which is involved in the active transport of iron siderophores and cobalamin .
