2.5.1.67 2 dimethylallyl diphosphate - 2.5.1.67 2 dimethylallyl diphosphate multistep cyclization cascade, biosynthesic pathway, and family tree of terpenomic diversity, overview 2.5.1.67 2 dimethylallyl diphosphate chrysanthemyl diphosphate synthase is an inefficient promiscuous enzyme, which synthesizes the irregular monoterpenes chrysanthemyl diphosphate (CPP), lavandulyl diphosphate (LPP), and trace quantities of maconelliyl diphosphate (MPP) from two molecules of DMAPP, and couples IPP to DMAPP to give GPP 2.5.1.67 2 dimethylallyl diphosphate reaction of EC 2.5.1.69, chrysanthemyl diphosphate synthase is an inefficient promiscuous enzyme, which synthesizes the irregular monoterpenes chrysanthemyl diphosphate (CPP), lavandulyl diphosphate (LPP), and trace quantities of maconelliyl diphosphate (MPP) from two molecules of DMAPP, and couples IPP to DMAPP to give GPP 2.5.1.67 6 dimethylallyl diphosphate - 2.5.1.67 dimethylallyl diphosphate + isopentenyl diphosphate reaction of EC 2.5.1.1, chrysanthemyl diphosphate synthase is an inefficient promiscuous enzyme, which synthesizes the irregular monoterpenes chrysanthemyl diphosphate (CPP), lavandulyl diphosphate (LPP), and trace quantities of maconelliyl diphosphate (MPP) from two molecules of DMAPP, and couples IPP to DMAPP to give GPP 2.5.1.67 additional information irregular monoterpenes are common in Chrysanthemum cinerariaefolium and related members of the asteraceae family, CPP is an intermediate in the biosynthesis of the pyrethrin ester insecticides 2.5.1.67 additional information relationships among chain elongation, branching, and cyclopropanation reactions in the isoprenoid biosynthetic pathway in wild-type and mutant cells, reaction mechanisms, detailed overview 2.5.1.67 additional information chrysanthemyl diphosphate synthase operates in planta as a bifunctional enzyme with chrysanthemol synthase activity. The NDXXD catalytic motif of CDS, under the lower substrate conditions prevalent in plants, also catalyzes the next step, converting CPP into chrysanthemol by hydrolyzing the diphosphate moiety. For the chrysanthemol synthase activity, dimethylallyl diphosphate competes with chrysanthemyl diphosphate as substrate
