Transcription unit          
Name: acrR
Gene(s): acrR   Genome Browser M3D Gene expression COLOMBOS
Note(s): In an experiment using increasing concentrations of tetracycline, the transcription of the acrR gene is induced in low concentrations (1.5 and 4 mg/L), but this induction decreases in high concentrations (10 mg/L) Viveiros M, Dupont M, Rodrigues L, Couto I, Davin-Regli A, Martins M, Pagès JM, Amaral L,2007
