Figure 4. Effects of co-expression of LcrF and LcrQ on T3SS.

Figure 4

(A) Secretion and expression of Yops and LcrQ in strains with overexpression of LcrF or LcrQ or co-expression of these two proteins. (B) Effects of co-expression of GST-fused LcrQ (G-Q) with LcrF on Yops and LcrQ expression and secretion. (C) Influences of over-expressing LcrF in an yscV mutant (ΔyscV 618–644) on expression of Yops. (D) Promoter activities of LcrF targets in ΔyscV 618–644 strains carrying pOVR-LcrF or pOVR200.
