This year iGEM Uppsala is Crafting Crocin. Crocin, an apocarotenoid (organic pigment) found in Crocus Sativus is responsible for the red color of saffron. Recent studies suggest that crocin has several medicinal properties helping with inflammation (1), neurodegenerative diseases (2) and more. We have worked on the pathway from zeaxanthin to crocin, extended from the pathway of farnesyl pyrophosphate (FPP) to zeaxanthin. By using synthetic biology for recombinant expression in E. coli we hope to reduce the price of the compounds within the pathway and open up the possibility for industrial and medicinal applications to be further explored.
Due to its color, it has great potentials as an organic dye for industrial applications. However, the labour-intensive production of saffron makes the product very expensive and the crocin pathway is poorly characterized. By using synthetic biology for recombinant expression in E. coli we hope to reduce the price of the compounds within the pathway and open up the possibility for industrial and medicinal applications to be further explored.
Previous work has been done with the five genes from FPP to zeaxanthin, but this operon is very large and unstable. We used chromosomal integration of these genes to ensure stable expression of zeaxanthin and it allows us to decrease the antibiotics usage. The iGEM Uppsala 2013 Team tried to express compounds from zeaxanthin but failed. To extend the pathway with the three-steps leading from zeaxanthin to crocin we successfully identified, assembled and characterized three enzymes in order to explore the possibility of using bacterial production of the color intense compounds.
