lacI:LVA (BBa_C0012) is being expressed from a constitutively active promoter. A terminator is put behind the coding region to prevent transcription of genes downstream of the repressor. The LVA-tag is a tag for degradation, and thus there is increased turnover of the protein. The device is meant to enable us to control the lactose promoter. However natural LacI proved to be more effective than the LVA-tagged. Has been sequenced and LacI:LVA function characterized by GFP fusion using FACS and growth experiment.
