Effect of DegPS210A on OmpC and OmpF. (A) Envelopes obtained from DegP+ OmpC1Cys (lane 1), DegP+ OmpC2Cys (lane 2), DegPS210A OmpC1Cys (lane 3), and DegPS210A OmpC2Cys (lane 4) were examined by SDS-PAGE. OmpC, OmpF, and OmpA bands were identified by Western blot analysis. (B) OmpC (solid bars) and OmpF (open bars) levels from panel A were quantified relative to OmpA.
