title: [Lon-protease participates in the regulation of transcription of the Lux-operon of Vibrio fischeri].
abstract: Lon protease of Escherichia coli specifically inhibits the activity of the regulatory protein LuxI responsible for synthesis of the autoinducer N-(3-oxo-hexanoyl)homoserine lactone. As a result, transcription of the right lux operon is initiated in lon+ bacteria much later than in lon- mutants. Lon protease does not affect the activity of LuxAB proteins (luciferase) and LuxC, LuxD, and LuxE proteins involved in synthesis of an aldehyde substrate for luciferase.
