Effect of depletion of ClpXP protease on the expression of the hilA gene in the absence of the hilC and/or hilD gene. (A) The expression levels of a lacZ fusion to the hilA promoter were assayed. The values represent the means and standard deviations for samples tested at least in triplicate. The strains used were CS2110 (clpPX+ hilC+ hilD+), CS2120 (ΔclpPX hilC+ hilD+), CS2732 (clpPX+ ΔhilC hilD+), CS3319 (ΔclpPX ΔhilC hilD+), CS2733 (clpPX+ hilC+ ΔhilD), CS3320 (ΔclpPX hilC+ ΔhilD), CS2815 (clpPX+ ΔhilC ΔhilD), and CS3321 (ΔclpPX ΔhilC ΔhilD). (B) Immunoblotting analysis of the cellular lysates using anti-HilA serum. The strains used were χ3306 (clpPX+ hilC+ hilD+), CS2007 (ΔclpPX hilC+ hilD+), CS2724 (clpPX+ ΔhilC hilD+), CS3322 (ΔclpPX ΔhilC hilD+), CS2725 (clpPX+ hilC+ ΔhilD), CS3325 (ΔclpPX hilC+ ΔhilD), CS2802 (clpPX+ ΔhilC ΔhilD), CS3328 (ΔclpPX ΔhilC ΔhilD), and CS2110 (ΔhilA).
