| Comments: |
Lavandulyl diphosphate is a monoterpene with a non-head-to-tail linkage. It is unlike most monoterpenoids, which are derived from geranyl diphosphate and have isoprene units that are linked head-to-tail. When this enzyme is incubated with prenyl diphosphate and 3-methylbut-3-en-1-yl diphosphate, it also forms the regular monoterpene geranyl diphosphate [2]. The enzyme from Artemisia tridentata (big sagebrush) forms both lavandulyl diphosphate and chrysanthemyl diphosphate (see EC 2.5.1.67, chrysanthemyl diphosphate synthase) when prenyl diphosphate is the sole substrate. |
