This page describes characterisation for part BBa K325909, the lux operon from Vibrio fischeri.
Description
This page described the lux operon from Vibrio fischeri. To relieve LuxR control we placed Lux C, D, A, B, E under the pBad promoter.
Arabinose to light
This page describes the relationship between Arabinose concentration in the medium with light output. We used a FLUOstar OPTIMA microplate reader to quantify the light output. Protocol and plate reader settings used are given below.

H-NS mutants
It has been shown that the expression of the Vibrio fischeri lux operon when cloned into E. coli was repressed. This repression was linked to the nucleoid protein H-NS. To investigate this effect we cloned the operon into mutant E.coli cells in which the expression of the H-NS protein had been modified. We used a FLUOstar OPTIMA microplate reader to quantify the light output. Protocols and plate reader settings used are given below.
