Toluene Degradation and Our Project

Pseudomonas putida F1 species degrades toluene with the help of the tod operon. Toluene dioxygenase and toluene cis-dihydrodiol dehydroxygenase transcribed from todC1C2BA and todD genes, respectively, facilitate the breakdown of toluene to 3-methylcatechol. Gerben J. Zylstra et al. successfully constructed the plasmid pTDG602 containing todC1C2BAD genes. To achieve complete degradation of toluene down to carbon dioxide and water, we focused on designing a plasmid containing todE and todF genes. After cotransformation of DH10B cells with pTDG602 and our plasmid, E.Coli should theoretically contain all the genes required to achieve complete degradation.

Submitted Part: TodE BioBrick (BBa_K1760001)

Final submitted biobrick is a coding sequence that contains a TetO promoter, RBS optimized by using Salis RBS caluclator and codon optimized todE gene for E.Coli. It plays a major role in degradation of toluene. Specifically, todE degrades 3-methylcatechol, a highly toxic intermediate into HOD. In pseudomonas putida species, HOD is aerobically metabolized through TCA cycle. Theoretically, a E.Coli MG1655 type bacteria containing todC1C2BADEF genes can degrade toluene through TCA cycle by using its own native enzymes.

This part is ordered in gene blocks and ligated by using Gibson Assembly by using . The design have been performed by Anthony Zhao, Seray Cicek, Umar Owadally, Katariina Jaenes, Matt D'lorio, ChungMin Lee, Drupad Rajyaguru who are wet lab team members of the iGEM Toronto 2015 team. See our part in the the registry: http://parts.igem.org/Part:BBa_K1760001

Additional Designs in Progress

In order to achieve complete degradation of toluene, we also constructed a codon optimized todF sequence. We tried to create a ligated plasmid containing todE, todF, optimized Salis RBS calculator and a tunable promoter to determine optimum transcription for DH10B cells. We used Ligase Cycling Reaction(LCR) in this process. Unique Nucleotide Sequences are added to ligating blocks to facilitate assembly of the plasmid without a secondary structure interference.

We also used BioBricks from the registry to design plasmids with different efficiencies by using RDP kit as shown below. In this process, we used promoter BBa_J23102 and RBS BBa_B0030.
