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

Rhodobacter sphaeroides Inoculation

Experimenter: Joe

Aim: A colony of Rhodobacter sphaeroides was inoculated in 5 mL LB culture for DNA extraction and grown at 30C

Results: Culture grew to high density after a couple days

June 30th

Miniprep 4CL

Experimenter: Joe

Aim: Miniprep 5mL innoculation of 4CL with Qiagen Miniprep Kit

July

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: PCR products were ran on a 0.8% agarose gel. 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: PCR products were ran on 0.8% agarose gel. 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

Results: DNA extraction was done following the above kit and diluted in TE buffer

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 Phenylalanine ammonia lyase (PAL), 4-coumarate 3-hydroxylase (4-CMH) from iGEM HQ

Experimenter: Joe

Ligate PAL/COMT/ATCCR1 constructs to Terminator/PSB1C3

Experimenter: Fisal

Aim: Ligate the ATCCR1 construct to PSB1C3 vector; ligation should disrupt the GFP protein yielding white colonies. Digested and purified PSB1C3 was acquired from Joe. Both PAL and COMT had been demonstrated through Colony PCR to have been successfully ligated to arabinose Inducible promoters, thus ligation of these constructs to the terminator mentioned above should yield a construct that we can test expression with. A Final ligation of TAL into PSB1C3 would also be attempted.

Results: The Ligations were run at room temperature for 4 hours and were then transformed into Chemically competent cells in accordance with our transformation protocol. In addition to the ligations mentioned above ATCCR1 was also ligated into a PSB1C3 +arabinose promoter vector. As it turns out TAL has two illegal cutsites, pst1 and EcoR1, that was overlooked, some of the digests performed used EcoR1 and Pst1 thus explaining some of the difficulties encountered.
