Team Cinnamaldehyde & Vanillin

Research Designs and Methods

The goal for cloning is to place each gene in the cinnamaldehyde pathways under a constitutive pTET and arabinose promoter pBAD for future characterization of each part. Our final construct should consist of a single pSB1C3 plasmid with all the genes inserted along with its ribosomal binding site and terminator:

Primers for the PAL/TAL, Ligase, and reductase genes are designed to yield PCR products containing all biobrick cut sites in the correct order: Eco R1, Xba 1, Spe1, and PstI. These PCR products could then be digested for ligation into available plasmids containing promoters (with or without rbs) and terminators.


June 28th

Transformation of 4-coumarate-CoA Ligase (4CL) and caffeic acid-O-methyl transferase (COMT)

Experimenter: Joe

Aim: Transform biobricks 4CL ( 2013 Distribution Kit, Plate 2, Well 17P) and COMT (2013 Distribution Kit, Plate 5, Well 19D) for miniprep and later amplification through PCR

Results: Transformation done according transformation procedures. Competent cells were plated on LB+ Amp plates and grown overnight at 37C. Only 4-CL grew overnight. No colonies were observed for COMT. Inoculated a colony of 4CL for miniprep

July 4th

PCR of 4-CL

Experimenter: Joe

Aim: PCR to amplify 4-CL from biobrick with biobrick VF2 and VR primers to confirm the size of 4-CL

Results: Multiple bands were seen due to possible mispriming of VF2 and and VR.


Retransformation COMT

Experimenter: Joe

Aim: Retransformation of COMT from biobrick registry and plated on LB agar + Amp

Results: Only one colony found on plate. This could have been the competent cells not being very competent.


July 5th

Digestion of 4-CL

Experimenter: Joe

Aim: Digest 4-CL to see if 4-CL is present in the pSB1C3 plasmid with EcoRI and PstI

Results: pSB1C3 plasmid is about 2070bp while 4CL gene is about 1656 bp. Digest was successful. Two bands were observed: one at 2kb and one at 1.7kb


Re-run PCR of 4CL

Experimenter: Joe

Aim: Re-run PCR of 4CL with fresh PCR reagents

Results: Mispriming seen but the brighter band is about 2kb, which is the size the PCR product of 4CL with the extensions from pSB1C3 (~1951bp)


July 6th

Genomic DNA extraction of R.sphaeroides grown on June 28th

Experimenter: Joe

Aim: Bacterial DNA extraction using QuickExtract Bacterial DNA Extraction Kit

July 8th and 9th

Inoculation of COMT and miniprep

Experimenter: Joe

Aim: Inoculated one colony of COMT in 5mL LB + Amp and grew overnight for Miniprep.

Results: Miniprepped the 5mL innoculation of COMT with Qiagen Miniprep Kit and eluted with 30uL of dH2O


Received PAL, 4-CMH from iGEM HQ

Experimenter: Joe

Aim: Plated cells received form iGEM HQ. These include BBa_K801091 (Phenylalanine ammonia lyase-PAL) and BBa_K238007 (4-coumarate 3-hydroxylase) which were plated on Chlor LB plates and Amp LB plates respectively.

Results: Cells grew on their respective plates and inoculated with 5mL of the LB on their respectively antibiotic. Miniprepped the 5mL inoculation of COMT with Qiagen Miniprep Kit and eluted with 30uL of dH2O
