Fig. 4: DNA binding capacity of CadC and CadC1-184.

EMSA results illustrate the interaction between the cadBA promoter and CadC1-184 fragment (a), full-length CadC (b), CadC1-184 with Zn2+ (c), and CadC with Zn2+ (d). FP assay assessing the binding affinity of cadBA promoter for CadC1-184 fragment and full-length CadC in the presence of Zn2+ (f) or absence of Zn2+ (e). Data are mean ± SD of n = 3 biologically independent replicates.
