Applications of BBa_K4117022

Experiment: Experiment:

1.synthesis of pathways to metabolism Δ9-THC. We design the Plasmids and had the company GENEWIZ synthesized them.

2.Construction of pathway to verify CYP2C9 extracellular secretion. We obtain the gene fragments of CYP2C9, ompT and His-tag by PCR from the CYP2C9. After the completion of PCR, electrophoresis is performed to determine the size of DNA, and then DNA fragments are recovered. Finally we insert it into the pET-Duet1 downstream of the T7 promoter and upstream of the T7 terminator to verify the external secretion of CYP2C19 under IPTG induction.

3.Verification of imported gene pathways. We transform E. coli BL21(DE3) competent cells with the prepared plasmid for overnight culture and preserve the engineered bacteria in glycerol and stored them at -80℃ for standby.

4.Feasibility experiments on IPTG induction. We select E. coli BL21(DE3) IPTG-induction E. coli BL21(DE3) strain and add 100μL 500mmol/L IPTG for each 50mL bacterium to induce the expression of CYP2C9 overnight. The fusion expression proteins are purified by his-tag protein extraction kit and verified by SDS-PAGE gel.

Result: We construct the Δ9-THC metabolism pathway of CYP2C9 which induced by Δ9-THC.

1. The verification of plasmids for correctness. We insert the gene fragments of CYP2C9, ompT and His-tag into the pET-Duet1 downstream of the T7 promoter and upstream of the T7 terminator, and verify the bacterial colony PCR products by gel electrophoresis to initially determine the correctness of the plasmid construction. After that we extract the plasmids and verify the correct construction of the plasmids by sequencing them by the company.

2. Protein expression, purification verification. The fusion expression proteins are purified by His-Tag protein extraction kit and verified by SDS-PAGE gel.The results show that the proteins are successfully expressed.
