SpoIIIJ and YqjG restore the defect in PMF generation due to YidC depletion. The ΔpH of IMVs was measured by using ACMA fluorescence in the presence of 1 mM ATP (A and B) or 1.25 mM NADH (C and D) added at the time indicated by arrow 1. Valinomycin (arrow 2) and nigericin (arrow 3) were each added at a final concentration of 1 μM. The ΔpH traces generated by wild-type IMVs (WT) and YidC-depleted IMVs (YidC-) are indicated by thin lines, and the ΔpH generated by YidC-depleted IMVs containing SpoIIIJ (A and C) and YqjG (B and D) are indicated by thick lines. a.u, arbitrary units.
