promoter nar(fnr regulated)


We add the promoter “Pnar”, in response to the RES-FNR oxygen regulator system of Bacillus Subtilis, to express phy(ycD) phytase efficiently in the absence of oxygen, and meanwhile express CI repressor protein to inhibit toehold switch-Dpnc downstream.

According to the paper, they have designed three kinds of strength of the promoter Pnar and applied them in E.coli successfully. The expression level of GFP in the control of high-strength promoter was 19.7 higher than the wild-type promoter.
