Design
BBa_K2500010: AND gate a
In 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
