Part:BBa_K3505034

Designed by: Asteria Tsapadikou   Group: iGEM20_Thessaly   (2020-10-20)


pAndersonJ23115:tetO:RBS-lacI-terminator


Usage and Biology

This parts consists of AndersonJ23115 promoter BBa_K3505012 , LacI BBa_K3505003 and Double Terminator BBa_K3505017. By this way ,as AndersonJ23115 is a strong constitutive promoter, LacI is constitutively expressed. LacI binds to lac operator and inhibits the expression of a desirable transcription unit.

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 alpha vector BBa_K3505009 and has overhangs compatible for GoldenBraid cloning.
