The immunoblot data in Fig. 4A was not obtained from a conditional secDF depletion strain Escherichia coli BL325 with a plasmid-borne copy of SecY(I91pBpa)EG as stated. The correct images representing SecD, SecF, SecY, and YidC levels in inner membrane vesicles of the conditional secDF depletion strain E. coli BL325 with a plasmid-borne copy of SecY(I91pBpa)EG are now shown. This correction does not affect the interpretation of the results or the conclusions of this work.
