Part:BBa_K2423000
CaCCD2 under the control of a constitutive promoter (BBa_J23106)
This part codes for carotenoid cleavage dioxygenase 2, a member of the CCD family. This enzyme catalyses the conversion of zeaxanthin into crocetin dialdehyde in Crocus ancyrensis through cleavage at the 7,8 and 7',8' position. The part contains a constitutive promoter, and a His tag for purification. A different version of this biobrick is BBa_K2423005, which is controlled by an inducible promoter.
