CsADH-2946 under the control of a constitutive promoter (BBa_J23106)
This part codes for aldehyde dehydrogenase 2946, which catalyses the conversion of crocetin dialdehyde into crocetin, using NAD+ as a cofactor, in Crocus sativus. It contains a constitutive promoter, as well as a His tag for easy purification. A version of this biobrick containing an inducible promoter is BBa_K2423007.
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, CsADH2946 catalyzes the second reaction in the zeaxanthin to crocin pathway.
