FAST reporter construct with PLac


Usage and Biology

This parts entry represents a FAST reporter construct under the regulatory control of the lactose-inducible PLac system from C. perfringens. The construct comprises the FAST reporter gene BBa_K2992000under the regulatory control of the BgaRL lactose inducible system from C. perfringens wherein the divergent PbgaRBBa_K2992020 and PbgaL BBa_K2992023 promoter sequences, coupled with their native 5’-UTR and RBS sequences BBa_K2992022[ https://parts.igem.org/Part:BBa_K2992024 BBa_K2992024] respectively control the transcription of bgaR and FAST. Transcription for bgaR is terminated by its native terminator sequence BBa_K2992021

FAST is one of the few fluorescent reporters available for effective use in anaerobic organisms. FAST is derived from Halorhodospira halophila and has been codon optimised for fluorescence studies in the genus Clostridium. In our project we couple FAST with the natural promoters of the BotR regulon thus linking reporter fluorescence with botulinum neurotoxin production. In doing so, we hoped to generate our surrogate host strain as a model for predicting neurotoxin production in foodstuffs following food manufacturing processes.
