, a vetispiradiene synthase
is an enzyme
of Egyptian henbane
the following chemical reaction
- trans,trans-farnesyl diphosphate vetispiradiene + diphosphate
Hence, this enzyme has one substrate, trans,trans-farnesyl diphosphate, and two products, vetispiradiene and diphosphate.
This enzyme belongs to the family of lyases, specifically those carbon-oxygen lyases acting on phosphates. The systematic name of this enzyme class is trans,trans-farnesyl-diphosphate diphosphate-lyase (cyclizing, vetispiradiene-forming). Other names in common use include vetispiradiene-forming farnesyl pyrophosphate cyclase, pemnaspirodiene synthase, HVS, and vetispiradiene cyclase. This enzyme participates in terpenoid biosynthesis.
