VANILLIN SYNTHESIS
Goal
Making vanillin from tyrosine in a five-step pathway.
Required
Biobricks:
- SAM8: : coding sequence without RBS
- SAM5: : RBS site + PstI restriction site removed
- COMT: : coding sequence without RBS
- FCS: : RBS + fcs in pSB1A2
- ECH: : RBS + ech in pSB1A2
Where from
- SAM8, SAM5, COMT, FCS, ECH will be sent to us from the French Lab from the university Edinburgh
Steps
- We will be working in three different stages
- Testing the transformation of tyrosin to ferrulic acid. The enzymes are put under a constitutive promoter and transcribed. Ferrulic acid concentrations are then measured with GC
- Testing the transformation of ferrulic acid to vanillin. The enzymes are put under a constitutive promoter and transcribed. Ferrulic acid concentrations are then measured with GC
- If both are tested and ok, they can be combined into one plasmid and again tested.
- Then, the locks need to be added.
- Testing the enzymes by detecting the endproducts through gaschromatography.
- One problem might be that the tyrosine of E. coli is depleted too fast
