FIG 5.

BsSatA and BaSatA impart streptothricin resistance to Salmonella enterica. Strains carrying a plasmid encoding BsSatA (pBsSATA1, circles), BaSatA (pBaSAT1, triangles) and those carrying the cloning vector (pCV1, squares) were grown in minimal medium, either lacking streptothricin (closed symbols; panels A and B) or challenged with 10 μM streptothricin (open symbols; panels C and D). l-(+)-Arabinose was present in the medium at 500 μM as inducer in panels B and D. The following strains were analyzed: JE22263 (ΔmetE2702 ara-9/pCV1), JE22334 (ΔmetE2702 ara-9/pBsSATA1), and JE24022 (ΔmetE2702 ara-9/pBaSAT1). Error bars are present, although in many cases they are too small to be visible.
