Part:BBa_K2992021
Usage
The BgaR-BgaL system of C. perfringens comprises the transcriptional regulator BgaR belonging to the AraC-family and the β-galactosidase BgaL which are transcribed in a regulated fashion from the divergent PgaR -PgaL promoter. The BgaR-BgaL system regulates the expression of carbohydrate metabolic genes in response to lactose concentrations (Hartman and Melville 2011). This part entry represents the transcriptional terminator found downstream of the stop codon for bgaR. The Plac system is comprised of the divergent PbgaR-PbgaL promoter and associated 5’-UTRs in conjunction with their cognate transcriptional regulator bgaR. The Plac system was used to drive lactose-dependent expression of botR (BBa_K2992002), which in turn, regulates the production of our reporter genes which we have placed under the control of a BotR-activated promoter (BBa_K2992028, BBa_K2992029, BBa_K2992036).

Secondary Structure
Characterisation
The Plac system is an inducible promoter system utilizing the lactose operon from C. perfringens. This allowed us to test the maximum and minimum reporter expression range, informing the design of our electornic nose. See our results page for more information. In our project, the Plac system was used to drive lactose-dependent expression of botR (BBa_K2992002) which in turn, regulates the production of our reporter genes which we have placed under the control of a BotR-activated promoter (BBa_K2992028, BBa_K2992029, BBa_K2992036).
