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.

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 5mL LB culture for DNA extraction

Miniprep 4CL

Experimenter: Joe

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


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.


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: 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.


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.


August 19th

Experimenter: Anna Müller

Aim: Check if Fisal’s ligations were successful: TAL in PSBIC3 and TAL with arabinose promoter with colony PCR

Results: 2 colonies were picked for each. No bands were seen on the gel. Ligations were unsuccessful.

August 21st

Experimenter: Anna Müller Aim: Ligate PAL and COMP to a constitutive promoter with RBS (.22A) Results: After transforming, 2 colonies were picked and PCR’d (21st Aug. and 26th Aug.). The gel confirmed the presence of both PAL (2100bp) and COMT (1001bp).
