Part: BBa_K1937003 (pNagA)
(Chassis E. coli, carrier plasmid pSB1C3, part destined for use in Bacillus subtilis)
Length: 1035 bp
Background: pNagA is the promoter of the NagA gene, which expresses a N-acetylglucosamine-6-phosphate deacetylasein in Bacillus subtilis (http://www.biocyc.org/gene?orgid=BSUB&id=BSU35010). In Bacillus subtilis, this promoter has been reported to induce expression in presence of N-acetylglucosamine 6-phosphate (Bertram et al., 2011: https://www.ncbi.nlm.nih.gov/pubmed/21602348). This NAG molecule is the major component of chitin, a characteristic molecule of fungi. This BioBrick is a part developed by the Toulouse 2016 iGEM team (http://2016.igem.org/Team:Toulouse_France)
This part:
The BBa_K1937003 part was designed to demonstrate the induction of pNagA by NAG. It belongs to the antifungal module in the Paleolitis project of iGEM Toulouse 2016 (http://2016.igem.org/Team:Toulouse_France).
The part include the pNagA promoter and its RBS (position 3,595,156 to 3,595,356 of the Bacillus genome). The promoter controls the expression of the RFP fluorescent reporter gene. A NheI restriction site has been placed before the RFP ORF to facilitate promoter swapping.
Validation:
The part was sub-cloned in the pSBBsOK-mini plasmid (BBa_K1937001) for validation (resulting in part BBa_K1937004). In presence of N-acetyl glucosamine in the media, the clones are expected to be red, and white without this substrate Nag.
We indeed observed intense red stains on the colonies with the pNagA promoter growing on NAG (as well as with the pNagP promoter, see part BBa_K1937006), albeit the expression is late during the colonies development and is heterogeneous.
Sequence:
Promoter NagP+RBS: 23-222
