botR integration module for C. sporogenes with native promoter, 5-UTR+RBS

Usage and Biology

This parts entry represents an integration module for the expression of botR from the pyrE locus of the C. sporogenes genome. This module comprises a strong clostridial terminator sequence Tfad to prevent polar transcription from pyrD [1] and the botR gene of<i>C. botulinum [2], under the regulatory control of its native promoter PbotR [3] and its associated 5’-UTR which contains the RBS [4]. An additional strong clostridial terminator was included to prevent polar effects for the transcription of pyrE and any downstream genes on the chromosome of C. sporogenes. In our project we use the transcriptional regulator BotR to control the regulation of our volatile reporter operons [add comp part hyperlinks] and our fluorescent reporter FAST [] through interaction with its own promoter sequence P<i>botrR [5] and PntnH [6] whose genes are cognate members of the BotR regulon. Doing so allows us to use our surrogate host strain C. sporogenes as a model system for predicting botulinum neurotoxin production following food manufacture, through the detection of our chosen reporters.
