Plac-RBS GB compatible with A1-B2

Promoter lac is a weak inducible promoter from the lactose operon. This part has no lactose operator, because our team needed only the promoter.

Usage and Biology

T5 promoter has been used for many years for protein expression in E.coli. Partial T5 promoter is used with the downstream Operator CuO.

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 cloned in pUPD2 BBa_K3505007 and has overhangs compatible for GoldenBraid cloning. The Promoter has position A1-B2.
