The response, measured as the fold of induction (mean fluorescence when salicylate is added/mean fluorescence for DMSO control) for salicylate concentrations ranging from 1-2000 μM added to E. coli cells harbouring the one-plasmid system grown in LB overnight. Filled diamonds are the data for wild-type DntR without the His6-tag, and open circles are the data for wild-type DntR with the His6-tag at its C-terminal.
