The sequences (compared to the sequence of wt DntR) of the original templates and the clones with >3-fold induction in response to DNT when grown in M9 listed together with the response to 500 µM DNT and 500 µM salicylate expressed as the fold of induction.

The mean fluorescence was measured for a cell population of 10 000 cells for each sample with the standard error based on at least three independent experiments shown in parenthesis. Clones are named after the library and sorting which they were isolated from followed by a unique clone label. The substitutions derived from the NtdR template are marked in bold.
