AND gate regulated by norR and esaR (two esaboxes)

AND gate constructed by placing 2 esaboxes with 15bp spacing in between, after the transcription start site of PnorV.

Design of AND gate. The spacing between the esaboxes is 15bp long. NRB;NorR binding site, Sigma54B; RNA polymerase binding site


We constructed a selection of AND gates responding to nitric oxide (NO) and 3OC6HSL (AHL). They were designed using the previously described NorV promoter Part:BBa_K1153000. This Promoter (from here on refered to as PnorV) is the native promoter controlling the nitric oxide reduction operon (norRVW) in E. coli [1]. Its transcriptional regulator, NorR, can bind to nitric oxide and activate gene expression. Using the distinct properties of esaboxes, PnorV was designed to also be responsive to AHL, giving it an AND gate behaviour. An esabox is an 18bp sequence to which the transcriptional regulator EsaR Part:BBa_K2116001 can bind. Transcription can be initiated by the specific AHL EsaR responds to [N-(3-oxo-hexanoyl)-L-homoserine lactone]. By placing one, two or three esaboxes at different positions in the vicinity of PnorV, different specificities for AHL and NO were reached. We created and characterized a collection of these kind of AND gates:
