UGTCs2 under the control of a constitutive promoter (BBa_J23106)

This part codes for a cytosolic glycosyltransferase found in Crocus sativus. The enzyme will catalyse the conversion of crocetin to α-crocin in the presence of UDP-glucose. It is a modified version of BBa_K1033112, with two stop codons and a SGGS linker for the His tag. BBa_K2423008 is a slightly modifed version of this part (it uses BBa_J04500 as a promoter and RBS instead).

Usage and Biology

Saffron, a well recognized but expensive spice, has not only uses in terms of cooking but compounds found in saffron have been shown to help with inflammation (1), neurodegenerative diseases (2) and more. Some of those compounds namely zeaxanthin, crocetin dialdehyde, crocetin and crocin are all a part of the same metabolic pathway in the plant specie Crocus Sativus. Not only are these compounds in saffron helpful in terms of their potential medicinal properties, but also the fact that they are very colorful makes them interesting as organic dyes for industrial purposes. These aspects are what drew us at iGEM Uppsala 2017 to work with the pathway from zeaxanthin to crocin in the BioBrick format, but also to integrate the metabolic steps in the pathway from farnesyl pyrophospate (FPP) to zeaxanthin on the chromosome of Escherichia Coli. The enzyme presented on this page, UGTCs2 catalyzes the third and final reaction in the zeaxanthin to crocin pathway.
