Part:BBa_K1937003:Design

=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.
