<!DOCTYPE html> Results

We successfully integrated the first five steps of the crocin pathway from FPP to zeaxanthin into the E. coli chromosome. The result is a E. coli strain expressing zeaxanthin. We have created sequence verified BioBricks of our enzymes in the extended crocin pathway: CaCCD2, CsADH2946 and UGTCs2. We have also characterized these enzymes with experiments and simulations. to purify and confirm activity of CsADH2946 as well as measuring the kinetic parameters of the enzyme

We created and combined the zeaxanthin producing strain with a plasmid containing the extended crocin pathway which gave us an E. coli strain including the entire production pathway from FPP to crocin. In the end, we were able to identify, create and extensively characterize the pathway for crafting crocin.

Successfully integrated five genes from FPP to zeaxanthin into the chromosome of E. coli.

-       <div class="text">We successfully integrated all five steps of the FPP to zeaxanthin pathway into the E. coli chromosome. The result is a E. coli strain expressing zeaxanthin. We have created six BioBricks in two versions. One version which is sequence verified, producing our enzymes CaCCD2, CsADH2946 and UGTCs2 respectively with inducible promoters. The other version include the three respective enzymes with a consecutive promoter. We have also modelled all our enzymes. In addition to this <b>we are the first</b> to purify and confirm activity of CsADH2946 as well as estimating the kinetic parameters.</div>
