ID 2.5.1.69 DE lavandulyl diphosphate synthase. AN FDS-5. CA 2 dimethylallyl diphosphate = (R)-lavandulyl diphosphate + diphosphate. CC -!- Lavandulyl diphosphate is a monoterpene with a non-head-to-tail CC linkage; it is unlike most monoterpenoids, which are derived from CC geranyl diphosphate and have isoprene units that are linked head- CC to-tail. CC -!- When this enzyme is incubated with prenyl diphosphate and isopentenyl CC diphosphate, it also forms the regular monoterpene geranyl CC diphosphate. CC -!- The enzyme from Artemisia tridentata (big sagebrush) forms both CC lavandulyl diphosphate and chrysanthemyl diphosphate (see CC EC 2.5.1.67) when prenyl diphosphate is the sole substrate.
