sfGFP under melibiose promoter
Design
Chromosomal copy of MelR transcription factor is sufficient to activate the melibiose MelAB promoter copied from E. coli K12 chromosome (upon addition of melibiose to M9 minimal medium or to a rich medium 2xLB [0,4%]), as well as shortened MelWT with removed PstI site. In both media induction is much weaker than that of arabinose or rhamnose induced promoters.

Results

MelWT [BBa_K1741003]
The sfGFP fluorescence [RFU] was measured using Tecan fluoremeter.
We also checked the tightness of our promoters.
All of our promoters are induced only by their respective sugars with a small exception of xylose promoters being slightly induced by arabinose and arabinose promoters being slightly induced by xylose. All of our promoters are repressed by glucose.
