AndersonJ23115:LacO:RBS GB compatible A1-B2

Constitutive Anderson BBa_J23115with Lac Operator and RBS BBa_B0034


Usage and Biology

This part is a constitutive promoter from Andesron family , J23115 , having downstream with a Lac Operator and RBS. The activity of this part is regulated by LacI BBa_K3505003. LacI binds to Lac Operator and inhibits the expression of the desirable transcription unit.



Design Notes

The sequence was domesticated . We removed BsmBI ,BsaI , BtgZI, BpiI sites in order to be compatible with GoldenBraid and MoClo. The sequence is cloned in pUPD2 BBa_K3505007 and has overhangs compatible for Golden Braid cloning. This has position A1-B3.
