Acetone pathway: ca_thl-ca_ctfAB-cp_TFdx

Promoterless acetone production pathway with C. acetobutylicum thl, ctfAB and adc genes.

Usage and Biology

This parts entry represents a promoterless acetone-production pathway for plasmid-borne expression in C. sporogenes. The entry comprises the thiolase gene thl BBa_K2992008 and acetoacetate decarboxylase adc gene </i> BBa_M36585 coupled with the two units of the ctfAB complex M36581 BBa_ M36581 and M36582 BBa_ M36582 which are all derived from C. acetobutylicum. Transcriptional termination for this synthetic acetone-production operon occurs through the activity of Tfdx from C. pasteurianum K2284012 BBa_K2284012. In our project we used genome-scale modelling to predict the necessary genes required to produce acetone in our chosen surrogate strain C. sporogenes. We sought to link acetone production with C. botulinum neurotoxin production by the integration of the neurotoxin transcriptional regulator botR onto the chromosome of C. sporogenes and by using promoter regions from the regulon of botR to control the acetone-production operons. In doing so, we hoped to generate our surrogate host strain as a model for predicting neurotoxin production in foodstuffs following food manufacturing processes.
