Figure 6. Reducing effects on yfiBNR activity.
A) Colony morphologies of yfiBNR/dsbA single and double mutants on LB Congo-red agar. Indication of the following abbreviations: ΔBNR – ΔyfiBNR, ΔB – ΔyfiBNR Tn7::yfiNR, ΔR – ΔyfiR, pR-flag – pMR-yfiR-flag, pdsbA – pME6032ara-dsbA, pME – pME6032ara. B) Immunoblots of PA01 and ΔdsbA with M2 and anti-YfiN antisera, showing levels of YfiR-flag and YfiN in whole cell lysates. C) The effect of increasing concentrations of DTT on attachment (bars), of the ΔBNR and ΔB mutants is shown relative to wild-type PA01. Curves represent relative optical density with standard errors.
