Part:BBa_K2971000

crtE from Deinococcus radiodurans

This part is the gene crtE (dr1395) from the extremophile Deinococcus radiodurans and encodes geranylgeranyl diphosphate synthase (GGPPS). GGPPS catalyze the condensation of farnesyl pyrophosphate (FPP) and isopentenyl pyrophosphate (IPP) into geranylgeranyl diphosphate (GGPP)[1]. GGPP is a precursor for the carotenoid biosynthetic pathway. The sequence has been codon optimized for expression in Escherichia coli and iGEM registry compatibility.

The UiOslo 2019 team used this gene in a composite part (BBa_K2971004) to produce the red pigment lycopene, in Escherichia coli, by inserting it into a vector along with the genes crtB and crtI.

We expressed the protein under the control of arabionose inducible promotor araC. We detected a faint protein band during our SDS analysis; it is likely the expression was not well-optimized.
