Figure 4. CovR protein is present in GBS strains expressing Q120P CovR.

Figure 4

Quantitative western analysis was performed on equal protein concentrations of GBS WT (A909), ΔcovR, ΔcovR/pCovR, ΔcovR/pCovRQ120P and RM003 using CovR antibody (lower panel). As a control, quantitative westerns were also hybridized to anti-Sigma A antibody (top panel). Note that CovR protein is expressed in all strains except the control GBSΔcovR strain indicating that the lack of CovR function in RM003 and ΔcovR/pCovRQ120P is not due to the absence of CovR protein.
