From: Isolation and identification of a TetR family protein that regulates the biodesulfurization operon
Biodesulfurization activity in E. coli BL21(DE3) pLysS when TetR family protein is supplied in trans via plasmid demonstrated by luciferase assay. a Graph showing the effect of different inducer concentrations (which corresponds to different TetR protein levels) on the luciferase activity. UI corresponds to uninduced samples. b Graph showing that TetR family protein expression (at 0.2 mM inducer concentration) does not affect growth and results in enhanced luciferase activity. The bar indicates the values obtained in luminometer and the lines indicate the growth (OD600). The experiment was performed in triplicates
