Design
BBa_K2500000: Bacterioferritin
Design notes: Codon-optimized for expression in E. coli Nissle.
Organism: E. coli Nissle
Original sequence: BBa_BBa_K1438001
Source: gBlock
BBa_K2500010: AND gate A
In the absence of high concentrations of L-lactate, LldR inhibitor proteins bind to the binding sites O1 and O2 surrounding the pLux promoter leading to the formation of a DNA loop. The pLux promoter is sequestered and inaccessible for transcription. In design A, the distances between the intercalated promoter and the binding sites were adapted from BBa_K1847007.
Registry: BBa_K2500010
BBa_K2500011: AND Gate B
In design B, each binding site was duplicated in order to achieve a potential zipper mechanism and stronger inhibition due to binding more LldR inhibitor proteins.
Registry: BBa_K2500011
BBa_K2500012: AND Gate C
In design C, an artificial spacer was embedded between the pLux promoter and the O2 binding site in order to influence the looping dynamics.
Registry: BBa_K2500012
