Part Collection
Parts Collection!
Our collection of parts contains genes required for modification of imidacloprid and degradation of 6-chloronicotinic acid (6-CNA). Final parts were assembled in pSB1C3 backbone harboring the chloramphenicol resistance gene and designed to have a LacI repressor, ribosome binding site, pTAC promoter, our degradation genes of interest, and double terminator.
The three composite parts each containing a cytochrome P450 (CYP) were designed to include an N-terminal pelB signal sequence to target expression to the periplasm and a cytochrome P450 reductase (CPR) for functionality of the CYP. The CPR was also made with it’s own designated rbs, promoter, pelB signal sequence, and terminator.
Composite parts with multiple degradation genes were designed so that each gene in the construct had a dedicated rbs, promoter, and double terminator.
Favourite Parts:
BBa_K1813026
BBa_K1813064
BBa_K1813067
Composite parts: Imidacloprid modification
BBa_K1813064 CYP6G1 from D. melanogaster with N-terminal PelB signal sequence and Musca domestica (house fly) cytochrome P450 reductase. CYP6G1 can convert imidacloprid to 4- and 5-hydroxy imidacloprid.
BBa_K1813065 CYP6CM1 from Bemisia tabaci with N-terminal PelB signal sequence and Musca domestica (house fly) cytochrome P450 reductase. CYP6CM1 can convert imidacloprid to 5-hydroxy imidacloprid.
BBa_K1813066 CYP2D6 from human with N-terminal PelB signal sequence and Musca domestica (house fly) cytochrome P450 reductase. CYP6G1 can convert imidacloprid to nitrosoimine derivative.
Composite parts: 6-CNA Degradation
BBa_K1813026 Cch2 is from Bradyrhizobiaceae strain SG-6C for conversion of 6-CNA to 6-HNA.
BBa_K1813020 NicC is from Pseudmonas putida KT2240 for conversion of 6-HNA to 2,5-dihydroxypyridine
BBa_K1813031 NicX is from Pseudmonas putida KT2240 for conversion of 2,5-dihydroxypyridine to N-formylmaleamic acid
BBa_K1813021 NicD is from Pseudmonas putida KT2240 for conversion of N-formylmaleamic acid to maleamic acid
BBa_K1813022 NicE is from Pseudmonas putida KT2240 for conversion of maleamic acid to maleic acid
BBa_K1813023 NicF is from Pseudmonas putida KT2240 for conversion of maleic acid to fumarate
Composite parts: Multi-gene Pesticide Degradation
BBa_K1813035 Consists of the genes required for degradation of 6-CNA to fumarate. These include genes coding for Cch2, to convert 6-CNA to 6-HNA, and NicCXDEF, the five enzymes required for degradation of 6-HNA to fumarate. The end-product, fumarate can be funneled into central metabolism.
BBa_K1813067 Contains one of the three CYPs investigated, CYP6G1, cytochrome P450 reductase, cch2, and the nicCXDEF cluster. This construct would allow for modification of imidacloprid to a less toxic form by CYP6G1, conversion of 6-CNA to 6-HNA by Cch2, and degradation of 6-HNA to fumarate by NicCXDEF pathway.
BBa_K1813066 As above, but with CYP6CM1 in place of CYP6G1.
BBa_K1813072 Also as above, but with CYP2D6 in place of CYP6G1.
Intermediate Composite Parts and Coding Sequences
Refer to the British Columbia 2015 iGEM team list of parts in the Standard Registry of Standard Biological Parts link here for all intermediate composite parts and coding sequences used in the design of our composite parts.
