Function

FPPS1_ARTSI Catalyzes the sequential condensation of isopentenyl pyrophosphate (IPP) with the allylic pyrophosphates, dimethylallyl pyrophosphate (DMAPP), and then with the resultant geranylpyrophosphate (GPP) to the ultimate product farnesyl pyrophosphate (FPP). Has a 4.5 time greater affinity for GPP versus DMAPP.[1] CHRDS_ARTSI Condenses two molecules of dimethylallyl diphosphate (DMAPP) to produce mainly an irregular monoterpene, chrysanthemyl diphosphate (CPP) and lower amounts of a branched monoterpene, lavandulyl diphosphate (LPP). CPP is a precursor of the pyrethrin insecticides. When incubated with isopentenyl diphosphate (IPP) and DMAPP, catalyzes three competing isoprenoid condensation reactions, a chain elongation to give geranyl diphosphate (GPP), a cyclopropanation to give CPP and a branching to give LPP.[2]
