Fig 9. FtsBE56A and FtsIK211I suppress FtsWA270T but not FtsWM269K.
(A) Spot test to assess the ability of FtsBE56A to suppress FtsWA270T and FtsWM269K. Plasmid pDSW208, pSEB429 or its derivatives carrying different ftsW alleles were transformed into strain SD367 [TB28, ftsW::kan/pSD257(pSC101ts, ftsW)] or SD368 [TB28, ftsBE56A, ftsW::kan/pSD257(pSC101ts, ftsW)] on LB plates with ampicillin, kanamycin and spectinomycin at 30°C. The spot test was performed as in Fig 5. (B) Spot test of the ability of FtsIK211I to suppress FtsWA270T and FtsWM269K. The test was done in strain SD292 [W3110, ftsW::kan recA56 slrD::Tn10 /pSD257 (pSC101ts, ftsW)] containing plasmid pLY91 (P204::ftsI) or pLY105 (P204::ftsIK211I). SD292 was transformed with plasmid pBAD33 carrying different ftsW alleles and transformants selected at 30°C. Test was done as (A) on LB plates with or without arabinose and IPTG at 30°C and 42°C.
