araC-ParaBAD:RBS GB compatible with A1-B1


Usage and Biology

The PBAD promoter, derived from the arabinose operon andis an inducible promoter for arabinose. The use of an inducible promoter provides a most reversible and flexible gene circuit and at the same time exhibits a higher efficiency and lower side effects as cell death.(Kallunki, Barisic, Jäättelä and Liu, 2019). The araC gene, is a regulatory gene and is located upstream of the L-arabinose operon, encodes a positive regulatory protein AraC, required for L-arabinose utilization in Escherichia coli. The araC gene has a constitutive promoter.

Design Notes

The coding sequence was domesticated . We removed BsmBI ,BsaI , BtgZI, BpiI sites in order to be compatible with GoldenBraid and MoClo. The sequence is presents in pUPD2 BBa_K3505007 and has overhangs compatible for Golden Braid cloning. The CDS has position A1-B2
