Design Notes
The goal of our project was to degrade inhaled carcinogens, so the initial substrate (benzene) must have strong evidence for being a carcinogen and must be commonly inhaled. Further, the final end products of the whole pathway must be incorporated into metabolism. While 2-hydroxymuconate-6-semialdehyde does not incorporate into metabolism, a second pathway can then convert 2-hydroxymuconate-6-semialdehyde to pyruvate and acetyl-CoA
Source
The TetR protein comes from the registry (BBa_C0040). The 4 genes for the benzene-1,2 dioxygenase BnzA, BnzB, BnzC, and BnzD) and the cis-1,2-dihydrobenzene-1,2-diol dehydrogenase gene (BnzE) come from Pseudomonas putida. The catechol-2,3-dioxygenase gene (CatE) comes from Bacillus subtilis.
