LacI device (constitutive promoter, RBS and terminator)
| Types | DnaRegion |
| Roles | Regulatory promoter |
| Sequences | BBa_K1088019_sequence (Version 1) |
Description
The trancsriptional repressor lacI (BBa_K1088018)under the constitutivly active promoter (BBa_J23106), with a RBS (BBa_B0030) and with a terminator (BBa_B1002).This device can be used to overexpress lacI with the purpose of repressing transcription from high-copy plasmids containting the lac promoter (BBa_R0010). The repression can be relieved by allosteric binding of IPTG to lacI, thereby promoting transcription from the lac promoter.
Notes
Used a strong terminator so that the composite part can be used in front of the lac promoter without unwanted transcription of the regulated gene.Source
