Part:BBa_K2992043

FAST reporter construct with Pfdx 5-UTR+RBS.

Usage and Biology

This parts entry represents a FAST reporter construct under the regulatory control of Pfdx. The construct comprises the strong clostridial promoter Pfdx BBa_K2992016 and its associated 5’-UTR containing the RBS BBa_K2992017 driving the expression of the fluorescent reporter gene FAST BBa_K2992000. Transcirptional 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.
