Part:BBa_K2992022

5-UTR containing RBS for bgaR from C. perfringens

Component of the divergent PbgaR -PbgaL promoter predicted to regulate bgaR in C. perfringens.

Usage and Biology

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 parts entry represents the RBS and 5’-UTR predicted to regulate 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).

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. See our results page for more information.
