Figure 4

Interaction of DauA with DctA/DcuS. (A) β-galactosidase activity was used to quantify the BTH results. BTH101 (cyaA − reporter strain) was co-transformed with the respective plasmid pairs. The activity measure for the pair DctA-T25/DcuS-18 was used as a positive control. All the results are the average of at least five independent biological repeats. Error bars represent standard error of the mean. (B) The background activity was measured by non-interacting pairs and was determined below 150 Miller units. The data presented are representative of one experiment.
