Part:BBa_K2992047

FAST reporter construct with Pha33 5-UTR+RBS

Usage and Biology

This parts entry represents a FAST reporter construct under the regulatory control of Pha33 for the hemagglutinin component of the Botulinum neurotoxin complex in C. botulinum. The construct comprises the promoter Pha33 BBa_K2992040 coupled with its associated 5’-UTR containing the RBS BBa_K2992041, driving the expression of the Fluorescence-Activating and Absorption-Shifting Tag protein (FAST) reporter gene BBa_K2992000. Transcriptional terminator occurs through the activity of the strong clostridial terminator TFad BBa_K2284012. 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.
