title: [The effects of the regulatory proteins RcsA and RcsB on the expression of the Vibrio fischeri lux operon in Escherichia coli].
abstract: A study was made of the effect of RcsA and RcsB on the Vibrio fischeri lux expression in Escherichia coli. RcsA suppressed the LuxR activity and thereby inhibited expression of the lux genes coding for luciferase and reductase. In osmotic shock, RcsA-RcsB activated lux expression and, consequently, bioluminescence of E. coli cells in the early log phase.
