Chrysanthemyl diphosphate synthase explained

Chrysanthemyl diphosphate synthase
Ec Number:	2.5.1.67

In enzymology, a chrysanthemyl diphosphate synthase is an enzyme involved in the biosynthesis of terpenoids. This enzyme is also known as CPPase. It catalyzes the chemical reaction shown below (color-coded to show how precursors link):

The substrate of CPPase is dimethylallyl diphosphate. The two products are diphosphate and chrysanthemyl diphosphate.

This enzyme is involved in the biosynthesis of pyrethrins, highly potent insecticides found in some flowers. The systematic name of this enzyme class is dimethylallyl-diphosphate:dimethylallyl-diphosphate dimethylallyltransferase (chrysanthemyl-diphosphate-forming).
