Description
The position 3&5 mutated promoter lux pR-3/5 is a product of site-directed mutagenesis of promoter lux pR (BBa_R0062). The promoter lux pR is based on the Vibrio fischeri quorum sensing gene promoters. The position 5 mutated promoter lux pR-3/5 gives a lower expression of downstream genes in an autoinduction system. In another word, the lux pR-3/5 has a lower efficiency than the lux pR(BBa_R0062). Similar to promoter lux pR, the expression is up-regulated by the action of LuxR protein combined with the signal molecule HSL.
Notes
We have generated two point mutants by site-directed mutagenesis from the sequence of lux pR(BBa_R0062). In these mutants, the G residue of position 5 was changed to a C and the C residue of position 3 was changed to a T respectively.
