PntnH

Promoter region for the non-toxic non-haemagglutinin component of the neurotoxin gene cluster in Clostridum botulinum.

Usage and Biology

Pntnh is found upstream of the 5'-UTR and RBS of the non-toxic non-haemagglutinin component (ntnh) of the neurotoxin gene cluster in C. botulinum. This promoter was used to drive expression of of the toxin regulator botR and our chosen reporter genes of interest which have been placed under the control of the neurotoxin and neurotoxin-associated promoters. Doing so allows us to link volatile reporter production with neurotoxin production following food manufacturing processes.

Characterisation

This basic part was characterised as part of our composite parts using 3 difference reporters: GusA (BBa_K2992039), FAST (BBa_K2992044) and acetone (BBa_K2992036 ). This part was used as a promoter which functions in both the Gram-negative E. coli and the Gram-positive Clostridium sporogenens. More information can be found on our Results Page
