FIGURE 1.

The Tat system is required for Salmonella resistance to protamine. A, protamine susceptibility screening for wild type (wt; 14028s), tatC (YS13007), and phoP (YS11590) on LB plates containing protamine (0 or 1.2 mg/ml). B, plasmid harboring a wild-type copy of tatC restores resistance to protamine. Shown is percentage survival of wild type carrying plasmid pBAD TOPO (vector) and tatC mutant carrying plasmid vector or pBAD-tatC after incubation with protamine (0, 0.8, 1.0, or 1.2 mg/ml). Data correspond to mean values from at least two independent experiments performed in duplicate. Error bars, S.D.
