Part:BBa_K2457000
araC + pBAD arabinose inducible promoter
Arabinose inducible promoter pBAD forward + araC regulatory reverse gene under control of pC promoter and tryptophan terminator sequence.
Figure 1: BBa_K2457000 Circuit.
Usage and Biology
Inductor: L-Arabinose
Repressor: AraC acts like repressor to both promoters (PBAD e PC) in glucose presence or L-Arabinose absence.
The BBa_K2457000 includes approximately 1298 nucleotides and is used to regule transgene expression in Escherichia coli bacterias. This construction is composed by the araBAD (PBAD) promoter, which produces medium force, the L-Arabinose operon, in 5’ → 3’ direction with a upstream native RBS, two regulatory sites: I1 and I2, and two operators sites AraO, O1 and O2. It is composed also by the promoter PC that transcribes the regulatory protein AraC gene, followed to tryptophan transcription terminator, in 3’ → 5’ (reverse) (KUHLMAN & COX, 2010).
