Part:BBa_K2992026
botR integration module for C. sporogenes with native RBS for polar transcription
Usage and Biology
This parts entry represents an integration module for the expression of botR at the pyrE locus of the C. sporogenes genome. This module comprises the botR gene of C. botulinum BBa_K2992002 coupled with its native RBS BBa_K2992011 to encourage transcription from the promoter of the pyrD gene following integration onto the chromosome of C. sporogenes. A strong clostridial terminator was included to prevent polar transcription of pyrE and any downstream genes on the chromosome of C. sporogenes BBa_K2992013. In our project we use the transcriptional regulator of neurotoxin production from C. botulinum, BotR, to control the regulation of our volatile reporter operons (hyperlink to comp parts) and our fluorescent reporter FAST BBa_K2992000 through interaction with its own promoter sequence PbotrR BBa_k299012 and PntnH BBa_K2992001 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.
