sfGFP under a short arabinose promoter s2 without O1 and O2

This, shortened version of araBAD promoter (BBa_K1481002) does not contain O1 and O2 regions, but still contains the CRP binding site.

Characteristics and results

AraWT - [BBa_K1481002]

The sfGFP fluorescence [RFU] was measured using Tecan fluorometer.

All of our arabinose promoters are induced by the arabinose and repressed by the glucose. Arashort1 works better than AraWT. On the other hand, Arashort2 is slightly weaker when compared to Arashort1, but still stronger than AraWT. Probably O1 and O2 regions that were removed in Arashort2 are necessary for the best promoter's performance.


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. Teamuampoznanpromoterscomparisongrpah.png
