Membrane insertion of −3M-PC-Lep, FoC, and CyoA-N-P2 is strongly inhibited in the CS YidC(P431L) mutant. (A) Signal peptide processing of PC-Lep in the YidC(P431L) mutant. JS7131 bearing both pACYC184-YidC(P431L) and pMS119-Pf3 P2 was grown and analyzed as described in Materials and Methods. (B) Signal peptide processing of −3M-PC-Lep in the YidC(P431L) strain. (C) Protease accessibility of Pf3 P2 in the CS YidC(P431L) mutant. (D) Protease accessibility of the FoC in YidC(P431L) mutant. (E) Signal peptide processing of preCyoA-N-P2 in the YidC(P431L) mutant. The control in panel A was prepared in strain JS7131 grown under YidC depletion conditions. The control in panel B was prepared in strain JS7131 grown under yidC-expressing conditions. The Pf3 P2 and CyoA-N-P2 controls in panels C and E, respectively, were produced in the JS7131 strain grown with or without glucose (Glu; YidC depletion) or arabinose (Ara; YidC expression).
