Table 1. Mutations that revert DMB inhibition. Characterization of DMB resistant gain-of-function (GOF) strains. All mutant strains were derivatives of S. Typhimurium strain JE9426, and details of their isolation are described in Materials and Methods.

Abbreviations: SD, standard deviation; NG, no growth (OD₆₀₀ < 0.25); TSS, transcription start site; RBS, ribosome binding site; UTR, untranslated region; CDS, coding sequence.
