This circuit incorporates the pBlind-EL222 system, which is sensitive to blue light. Constitutively expressed EL222 can activate pBlind under blue light, resulting in increased expression of curli fibers and AG43 (this part contains two transcriptional units with pBlind. The first is pBlind-curli, and the second is pBlind-AG43). To assemble this circuit, we utilized 3G DNA assembly, which required individual 3G-compatible DNA parts (BsaI cutsites and proper sticky ends) as well as transcriptional units flanked by the proper Universal Nucleotide Sequences (UNS). To construct the transcriptional unit containing the synthetic curli circuit, we assembled csgBAC and csgEFG (which are divergent in E. coli) together, linking them with an RBS before csgE. This assembly required the creation of new sticky end (sticky end alpha, see parts pages BBa_K3059626, BBa_K3059627, and BBa_K3059612) in addition to William and Mary 2018 iGEM's sticky ends A-E.

Constitutively expressed EL222 can activate pBlind under blue light, resulting in increased expression of curli fibers and AG43 (this part contains two transcriptional units with pBlind. The first is pBlind-curli, and the second is pBlind-AG43).
