Web25 Nov 2015 · B. The re-engineered ftsZ sup9 mutation is sufficient for benzamide dependence. Strains DWA458 (ftsZ cat[FtsZ WT]) and DWA455 (ftsZ cat[FtsZ E251K]) (Site-directed-mutant; SDM) were streaked on NA + Cm in the absence and presence of either 3-MBA (10 mM) or 8J (2 μg ml −1), as indicated. Plates were photographed after … Web19 Sep 2008 · FtsZ is an essential bacterial guanosine triphosphatase and homolog of mammalian β-tubulin that polymerizes and assembles into a ring to initiate cell division. We have created a class of small synthetic antibacterials, exemplified by PC190723, which inhibits FtsZ and prevents cell division.
