Transcription of the proU operon of Escherichia coli is induced several hundred-fold upon growth at elevated osmolarity, but the underlying mechanisms are incompletely understood. Three cis elements appear to act additively to mediate proU osmoresponsivity: (i) sequences around a promoter, P1, which is situated 250 bp upstream of the first structural gene proV; (ii) sequences around another (sigma 70-dependent) promoter, P2, which is situated 60 bp upstream of proV; and (iii) a negative… CONTINUE READING
